Q2-Consider a Carnot heat-engine cycle executed in a steady-flow system using steam as the working fluid. The cycle has a thermal efficiency of 30 percent, and steam changes from saturated liquid to saturated vapor at 275°C during the heat addition process. If the mass flow rate of the steam is 3 kg/s, determine the net power output of this engine

Need help with this engineering problem.

2. A Rankine cycle is characterized by turbine inlet conditions of 10 MPa and 500°C. The condenser pressure is 6 kPa. The heat transfer to the steam in the boiler occurs at the rate of 7.0 X 100 kW. The cooling water in the condenser increases in temperature from 20⁰ to 30°C. Determine (a) the net power produced; (b) the cooling-water flow rate in kg/s; (c) the cycle thermal efficiency.
