In a steam turbine installation running on ideal Rankine cycle steam leaves the boiler at 10 MPa and 700°C and leaves turbine at 0.005 MPa. For the 50 MW output of the plant and cooling water entering and leaving condenser at 15°C and 30°C respectively determine, (a) the mass flow rate of steam in kg/s (b) the mass flow rate of condenser cooling water in kg/s c) the thermal efficiency of cycle d) the ratio of heat supplied and rejected (in boiler and condenser

3. In a steam turbine installation running on ideal Rankine cycle steam leaves
the boiler at 10 MPa and 700°C and leaves turbine at 0.005 MPa. For the 50
MW output of the plant and cooling water entering and leaving condenser at
15°C and 30°C respectively determine,
(a) the mass flow rate of steam in kg/s
(b) the mass flow rate of condenser cooling water in kg/s
(c) the thermal efficiency of cycle
(d) the ratio of heat supplied and rejected (in boiler and condenser
respectively).
Neglect K.E. and P.E. changes.
