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.

A steam power plant operates on a regenerative Rankine cycle.
Steam enters the turbine at 6 MPa at 700 ºC and the condenser at 10
kPa. Turbine has isentropic efficiency of 85% and pumps have
isentropic efficiency of 90%. Steam is extracted from the turbine
at 0.6 MPa to heat the feedwater in an open feedwater heater. Water
leaves the open feedwater heater as saturated liquid.

A micro gas turbine is designed to operate on the regenerative
Brayton cycle and is sized to produce 400kW of net
electric power. Air enters the compressor at
