A steam power plant operates on an ideal reheat Rankine cycle and uses water as the working substance. Steam enters the high-pressure turbine at 12.0 MPa and 500 °C where it expands to a pressure of 2.0 MPa. After which, it is reheated to 500 °C and then expands again in the low-pressure turbine to a pressure of 10 kPa. Then, it enters the condenser and leaves as saturated liquid. It is then pumped into the boiler back to a pressure of 12.0 MPa. Assuming all processes are ideal, then the pump work is nearest to:
