Q2 Draw a typical layout of a steam power plant. Explain the main features of layout.
Q3 A hydro plant operates under an effective head of 100 m and a discharge of 200 m3/sec.If the efficiency of turbine alternator set is 0.9, find the power developed.
Q4 A 500 MW nuclear reactor uses natural uranium as fuel. Assuming an overall efficiency of 34% and a load factor of 100% find the fuel used in a year.
Q5 Discuss with the help of suitable diagram, the operation of gas turbines in Open and Closed cycles.
Q6 Discuss the various types of pollution caused by steam and nuclear power plants. How this pollution can be reduced?
SECTION-C
Q3. Attempt any TWO questions. 2×10=20
Q7 A hydro electric station is designed to operate at a mean head of 210 m and fed by a reservoir having a catchment area of 1000 km2 with an annual rainfall of 130 cm of which 75% is available for power generation. The expected load factor is 75%. Allowing a head loss of 5 m and assuming efficiency of turbine and generator to be 0.85 and 0.9, calculate suitable MW rating of the station. Also comment on the type of turbine to be used.
