## Homework Statement

Given:

A reheat Rankine cycle

- Steams enter the high-pressure turbine at 12.5 MPa and 550C

- It leaves at 2 MPa

- Steam is reheated at constant pressure to 450C before it expands in the low pressure turbine

- Isentropic efficiency of turbine = 85%

- Isentropic efficiency of pump = 90%

- Steam leaves the condenser as saturated liquid

- moisture content of the steam at the exit of the turbine is not to exceed 5%

- mass flow rate is 7.7 kg/s

Find the condenser pressure

Net power output

Thermal efficiency

## Homework Equations

## The Attempt at a Solution

I already got the enthalpy of the inlet of high pressure turbine, at reheat, and at the inlet of the low pressure turbine. After that, I'm stock I do not know what should I do next. I do everything I know.

The answers are 9.73 kPa, 10.2 MW, and 36.9%
