Arsenal win at Fulham in their first match of the season

Arsenal win at Fulham

Fulham started their premier league campaign on a disappointing note as visiting Arsenal defeated them 3 nil.

Fulham started with hope as they pressed Arsenal in the first 10 minutes.

However, Arsenal scored against run of play in the 10min as fullam failed to clear their lines. Keeper deflected  Willian’s strike into the waiting legs of Alexandre Lacazette to slot home.

Arsenal continued dominating after their first goal. Fulham under pressure forced a foul on Lacazette in front of the 18yard at 26minute.

As a result,new signing Willian almost scored his debut goal from free kick that hits the woodwork at 27minute.

Arsenal then created several chances and Fulham were lucky to be one goal down at 42 minutes into the match.

Fulham rallied in closing stages of first half but scores end 0-1 at first half

Second half started with Arsenal pressing. The search for a second did not take long as Gabriel scored his debut goal from a poorly defended corner just 4 minutes into the second half. 0-2 Arsenal.

Arsenal now on a roll and get another goal scored by Pierre Aubameyang in the 57minute after a cross from Willian.

Willian did not score on his debut for Arsenal but had a good game. He was central to all 3 goals scored.

Arsenal now on top of the premier league table with 3 points.

Cultivating a small scale maize plantation

Harvested maize
Maize

Maize (corn) is a very popular crop that is easy to cultivate. It takes  about 3 months for the crop to mature for harvest. And if  you require drier grains,wait till after four months.

Health benefits of maize

Maize has been a stable source of food for mankind. It is very rich in carbohydrates and vitamins. It also contains, to a lesser degree; protein, sugar, fiber and fat.

Uses of maize as Food

Cooked corn starch is very nutritious for adults and children. A very nutritious food for babies from 6 months upward. Infact corn food products are a large content of baby/toddler food. Some common maize food products are corn flakes, corn starch, cornflour used in making bread, doughnuts, pancakes and much more.Freshly cooked or roasted  maize is a very popular snack. The application of maize in different food products is extensive.

Saving cost

If you consume a lot of cooked or roasted corn, corn starch or as feed for  chickens, it will be a good idea to have a small corn farm.  With half to one plot of land, you can reduce the cost of your maize consumption.if you have undeveloped land property or a large compound, you can cultivate maize. Maize plantation on a plot of land can yield over 70kg of grains.

How to plant corn

Maize plantation
Maize plantation

First things first; prepare the land for planting. The land must be cleared of weeds.You may make heaps to protect the crop from top soil wash off due to rain.

You can obtain planting seeds from grain sellersor agricultural institutes. Make sure you plant healthy seeds.You can plant about three seeds together and at a space of about 0.5 meters from another set.

Make sure your plantation is free from goats and other herbivorous animals.you can also protect the plants from pest by using agricultural insecticide.

Hydroelectric Power Systems

hyro electric dam
Hydro electric dam

Hydroelectric power plants convert potential and kinetic energy of water into electricity.

In hydroelectric production, potential energy of water is created by the construction of large dams. The dams hold the water at a greater height than the water level at the turbines.

Water is the greatest contributor of renewable energy to the world electricity generating system.

The common unit of measurement used to indicate the installed capacity of a hydroelectric power station is Megawatts.

Types of hydroelectric power plants

Based of design, hydro electric power plants are broadly divided into 2 types;

  1. Impoundment power plant
  2. Diversion power plant.

In the impoundment type of power plant, All water coming into the plant is dammed. The dammed water creates the head needed to power the hydro plant.

Impoundment  type of Hydro dam
Impoundment type of Hydro dam

In the diversion type, the water coming to the plant is partially dammed, some water is allowed to flow back into the river immediately while the rest is used to power the hydro plant.

Head and tail water

 In a hydro power plant system, the dammed water upstream is known as Head water and the water on the other side of the dam is known as Tail water. The difference between the top of the head water and that of the tail water is called pressure head.

Components of hydroelectric power plant

Trash rack; when water is coming fresh from the dam it needs to be cleared of big debris such as wood , plastic bags etc. the duty of the trash rack is to remove these.

Inlet gate; after water have been processed to remove debris, it then passed through the inlet gate. The inlet gate is used to regulate water flow into the turbines

Water conductors; water conductors are equipment used to convey water within the hydo electric power system. Example include; penstock, draft tube, scroll case, spill way, canals etc.

Penstock; the main pipe that conveys water to the turbine is known as penstock. It is a pressurized water conductor.

Spill way;  a spillway is a water conductor used to prevent overflow of dammed water

Runner; the runner is part of the turbine system and it rotates as water from the penstock passes through it at high pressure

Power house; the power house houses the turbine, electric generators, transformers and other electric generating equipment

Open air switch yard; when the electrical transmission equipment is installed in open air, it is called an open air switch yard.

How a hydroelectric turbine works

Water with high pressure head on the upstream side of the dam is lead through large penstock pipe. Before the water get to the turbine it passes through a scroll case. The scroll case is a large curved pipe that helps the flowing water to efficiently rotate the turbine. The turbine is connected to the generator through a shaft. so  as the turbine rotates, the connected generator also rotates  producing electricity.

Advantages of hydroelectric power plant.

  1. It is a completely green process
  2. It is a very efficient way of generating electricity.

Disadvantages of hydroelectric power plant

1. It is always necessary for settlement around the dammed area relocate. This is because water required to run hydroelectric plants is extremely large and dammed water will cause flooding of the settlement.

2. It is capital intensive. This is because the hydro dams constructed are extremely large.

Types of hydro power plants

  1. Impoundment type power plant. This type of power plant utilizes a dam to impound large amount of flowing river water. The dammed water is the potential energy necessary to power the hydro plant. The different type of dams that could be used include; gravity, reinforced concrete, buttress, rock filled or earth dams.
  2. Diversion type power plant( run of the river). In this case, the river water is partially dammed, only part of the flowing water is utilized to produce electricity.
  3. Tidal water plant. This process works based on tidal action of water. it helps create a height difference on either side of the turbine, this pressure difference cause water to flow through the turbine rotating it.
  4. Pumped storage power plant. This type of plant basically consists of very large reservoir of water held at a very high level. The stored water is then made to flow downwards through a penstock pipe to run the turbine and generate electricity. After reservoir is depleted, the water is pumped back again and the whole process is repeated. Pumped storage power plant is a type of standby power generator.Its acts as a supplement and is usually made available to the national grid during peak hours

Types of turbines

Broadly of two types;

  1. Reaction turbine
  2. Impulse turbine

The reaction turbine are pressure turbines. When water flow through this turbine, it creates a pressure differential which causes the turbine to rotate.

Impulse turbine are pressure-less turbines. It rotates due to the kinetic energy given to it by a jet of water as its hits the blades.

Types of turbine runners

There are many types of turbine runners, however, the 3 most commonly used are;

  1. Kaplan runner
  2. Francis runner
  3. Pelton runner

Kaplan runners are types of turbine runners that can operate with medium to high water flows and efficient at low pressure heads. Kaplan runners are reaction  runners because the pressure difference of the water flowing through the blades causes it to rotate.

Kaplan runner
Kaplan runner

Francis runners  are reaction runners and can operate within a wider range of pressure heads than the Kaplan runners.

Francis runner
Francis runner

Pelton runners are only adequate for very high flows and operates within a narrower range compared to the Kaplan and Francis runners.
