Power Generation MCQ Part 2
Most advantageous Power Generation from Sea Water
Which method of generating electric power from seawater is more advantageous:
- Ocean currents
- Wave power
- Tidal power
Correct answer: 3. Tidal power
Of three mentioned methods of Power Generation water bodies, the method of generating power from tidal is most efficient.
Which type of alternator is used in Hydropower plants
Which type of alternator is used in Hydropower plants:
- Salient pole alternator
- Non-salient alternator
- Turbo alternator
- None of above mentioned
Correct answer: 1. Salient pole alternator
Hydropower plants usually employ salient pole rotors. Hydraulic turbines usually operate at lower RPM. Therefore larger number of poles are required to obtain the required frequency.

Good to know:
Which part of the thermal power plant has steam pressure less than that of atmosphere
Which part of thermal power plant has steam pressure less than that of atmosphere:
- Superheater
- Boiler
- Condenser
- All have equal pressure
Correct answer: 3. Condenser
After leaving the last stage blades of the turbine the steam entering into the condenser a will posses the lowest pressure. So we can say the condenser of the thermal power plant has steam pressure less than that of the atmosphere

Chemical composition of coal is determined by which analysis
Chemical composition of coal is determined by which analysis:
- Proximate analysis
- Ultimate analysis
- Gross analysis
- Hardgrove grindability
Correct answer: 2. Ultimate analysis
Ultimate analysis determines the amounts of the major elements in coal such as: carbon, hydrogen, nitrogen, sulfur, oxygen
Coal power plants work on which cycle
Coal power plants closely work on which cycle:
- Brayton cycle
- Otto cycle
- Rankine cycle
- Atkinson cycle
Correct answer: 3. Rankine cycle
Coal power plants work on Rankine cycle
Here the fuel is used to produce heat within a boiler which in turn converts water into steam which then expands through a turbine producing useful work. Rankine cycle was developed in 1859 by Scottish engineer William J.M. Rankine and is named after him.
