Q:

Hydroelectric power plant is __________

A) Non-renewable source of energy B) Conventional source of energy
C) Non-conventional source of energy D) Continuous source of energy
 
Answer & Explanation Answer: B) Conventional source of energy

Explanation: Hydroelectric power plants are conventional source of energy. About 16.6% of total electricity and about 70% of total renewable energy of world is provided by hydroelectric power plants. They are not Non-renewable because water is inexhaustible. It is not continuous source of energy because its output fluctuates with change in flow rate of water with season.

Q:

The amount of electrical energy that can be generated by a hydroelectric power plant depends upon ___________

A) Head of water B) Quantity of water
C) Specific weight of water D) Efficiency of Alternator
 
Answer & Explanation Answer: B) Quantity of water

Explanation: Potential energy of large quantity of stored water is used by hydroelectric power plant to generate electrical energy. Head of water is important to get kinetic energy from that potential energy. Efficiency of alternator represents that what percentage of input mechanical power it can convert into electrical power.

Q:

Which of the following is the correct equation for the electrical power generated by the hydroelectric power plant?

A) 75×0.736 wQH? Watt B) (7.5/0.736) × wQH? Watt
C) 0.845 ×wQH? Watt D) 9.81 ×wQH?
 
Answer & Explanation Answer: C) 0.845 ×wQH? Watt

Explanation: Rating of any power plant is expressed by its maximum output power. These are large quantities so rating is given in mega watts.The electrical power generated by this plant is proportional to specific weight of water(w), water head(H), generation efficiency(?), flow rate of water(Q) and acceleration due to gravity.
