Q4. In a steam plant, using reheat, the turbine receives the steam at a pressure and temperature of 20 bar and 400℃ respectively. The steam expands isentropically in the first stage until it is just dry saturated.

It is then reheated at constant pressure to 400℃ and is expanded isentropically in the second stage to a condenser pressure of 0.04 bar.

The feed pump work cannot be neglected, there is no undercooling in the condenser and the steam flow rate is 4. 86 tonne per hour.

Calculate EACH of the following:

a) The power output (14)

b) The specific steam consumption. (2)
