Question

A steam turbine is to operate on a simple regenerative cycle. Steam is
supplied dry saturated at 40 bar, and is exhausted to condenser at 0.07 bar.
The condensate is pumped to pressure of 3.5 bar at which it is mixed with
bleed steam from the turbine at 3.5 bar. The resulting water which is at
saturated temperature is pumped to boiler. For the ideal cycle calculate,
neglecting the feed pump work.
