A steam power plant operates on a thermodynamic cycle in which water circulates through a boiler, turbine, condenser, pump, and back to the boiler. For each kilogram of steam (water) flowing through the cycle, the cycle receives 2000 kJ of heat in the boiler, rejects 1000 kJ of heat to the environment in the condenser, and receives 10 kJ of work in the cycle for stage one pump and another 10 kJ of work in the cycle for second stage one 1. Determine the work done by the steam in the turbine, in kJ/kg. 2. Determine the thermal efficiency for this cycle.

A steam power plant operates on a thermodynamic cycle in which water circulates
through a boiler, turbine, condenser, pump, and back to the boiler. For each
kilogram of steam (water) flowing through the cycle, the cycle receives 2000 kJ
of heat in the boiler, rejects 1000 kJ of heat to the environment in the condenser,
and receives 10 kJ of work in the cycle for stage one pump and another 10 kJ of
work in the cycle for second stage one
1. Determine the work done by the steam in the turbine, in kJ/kg.
2. Determine the thermal efficiency for this cycle.
