g ) Water is the working fluid in an ideal regenerative Rankine cycle with one closed feedwater heater. Superheated vapor enters the turbine at 16 MPa, 560 oC, and the condenser pressure is 8 kPa. The cycle has a closed feedwater heater using extracted steam at 1 MPa. Condensate drains from the feedwater heater as saturated liquid at 1 MPa and is trapped into the condenser. The feedwater leaves the heater at 16 MPa and a temperature equal to the saturation temperature at 1 MPa. The mass flow rate of steam entering the first-stage turbine is 120 kg/s. Determine (a) the net power developed, in kW.

Answer:

146494 kw

Explanation:

Given data:

Turbine inlet pressure ( p1 ) = 16 MPa

Turbine inlet temperature ( T1 ) = 560°C

condenser pressure : P3 = 8Kpa

Extracted steam at pressure ( P2 ) = 1 MPa

mass flow rate of steam ( m ) = 120 kg/s

a) The net power developed

= 146494 kw

note: values of    h1, h2,  y, Wp   are all calculated values not included in the solution to make the solution less cumbersome.
