Q. 1 a
Steam is supplied, at 40 bar and specific entropy of 6.0696 kJ/kg-K, to a turbine,
condenser pressure is 0.036 bar and enthalpy at exit of feed water pump is 117.84 kJ/kg.
If the plant operates on Rankine cycle, draw the cycle on T-s diagram and calculate, per
kilogram of steam:
i. The Rankine efficiency (consider pump work);
ii. Work ratio
iii. Specific steam consumption
Q. 1b Consider the steam enters the turbine with pressure of 40 bar, entropy of 7.0922 kJ/kg-K,
and condenser pressure of 0.0036 MPa, draw the cycle on T-s diagram and calculate the
cycle efficiency, work ratio, and specific steam consumption.
In a certain steam plant the turbine develops 703.72 kJ/kg. The heat supplied to the
steam in the boiler is 2800 kJ/kg, the heat rejected by the steam to the cooling water in
the condenser is 2100 kJ/kg and the network of the cycle is -995 kW. Calculate the
pump work in kJ/kg and steam flow rate.
Q2. b
A mass of gas, at an initial internal energy of 300 kJ, is allowed to expand behind a
piston until its internal energy is 200 kJ; the values for final pressure and volumes are
4.59 bar and 0.148 m³ respectively; the law of expansion is PV = C, calculate:
Q3.
The work done;
• The initial volume.
