Making Water Turbines Most Energy Efficient How does a wind turbine’s output vary with wind pressure (height of water)‚ the flow rate‚ size of the motor‚ and type of blade? Introduction There are many types of energy used today: Fossil fuels‚ coal‚ nuclear energy‚ solar energy‚ geothermal energy‚ hydrogen energy‚ hydroelectric energy‚ wind energy‚ and biofuels and biomass. Non-renewable energy sources such as fossil fuels and coal are diminishing since it cannot be recycled‚ unlike wind energy

EXPERIMENT 1: WATER CRYSTALIZATION OBJECTIVES: To determine the percentage of water in aluminium sulphate hydrate To calculate the water of crystallization for aluminium sulphate hydrate To prove that a hydrate solution will lose some of it mass after heated INTRODUCTION A hydrated salt is a crystallize salt molecule that is weakly attached to a certain number of water molecules. Salt is created when an acid’s anion (negative ions) and a base’s cation (positive ions) are combined to produce

Tap Water Vs Bottle Water Tap Water: Tap water is the most efficient water available. Unfortunately‚ it is also vulnerable to occasional contamination. This is usually locally due to damaged pipes. This type of problem can be fixed in a timely manner. For the most part‚ the water is not much different from bottled water. It can be consumed directly from the pipes without harm. Even when the water is contaminated it is usually not fatal. Water pipes efficiently carry water across the nation as

Water resources should be nationalised If the rivers are Nationalized we can get a massive improvements of Agriculture over complete India and there will be more productivity and consumer will get all goods at very cheaper price and can export too. According to me nationalization of water resources has its own pros and cons. The brighter side promises reduced inter -state conflicts‚ lower exploitation by individual states‚ higher portion of water available to farmers and greater monetary

property of water is that it is an excellent solvent. This is because of the chemical composition and physical attributes of water. Since water is polar‚ it allows water molecules to become attracted to different molecules. The attraction can be so powerful that it can disrupt the attractive forces of the different molecules. For example‚ water can be heavily attracted to salt that it can disrupt the forces that hold sodium and chloride‚ therefore dissolving it. The second property of water is its high
