Question:

For the steam power plant shown in Problem 4.118, assume that the cooling water comes from a lake at 15◦C and is returned at 25◦C. Determine the rate of heat transfer in the condenser and the mass flow rate of cooling water from the lake.


Data from Problem 4.118,

The following data are for a simple steam power plant as shown in Fig. P4.118. State 6 has x6 =0.92 and velocity of 200 m/s. The rate of steam flow is 25 kg/s, with 300 kW of power input to the pump. Piping diameters are 200mmfrom the steam generator to the turbine and 75 mm from the condenser to the economizer and steam generator. Determine the velocity at state 5 and the power output of the turbine.
