Mechanical Engineering

Ina double flash geothermal power plant, the high-pressure separatoris operating at 1 MPa and the adiabatic low-pressure separator isoperating at 300 kPa. The steam quality entering the adiabatichigh-pressure separator is 0.3. The mass flow of saturated liquidleaving the low-pressure separator is 15 kgs. The exit pressure ofthe steam turbine is 15 kPa and the turbine isentropic efficiencyis 0.8. Calculate
a. The mass flow at the turbine exit
b. The mass flow rate entering the high-pressure separator.
c. The production well pressure and temperature
d. The turbine high pressure and low- pressure poweroutputs
e. Temperature of the geofluid entering the reinjection well(Neglect pumps work )
