1. The problem statement, all variables and given/known data How can you determine the mass flow rate, given that net power output is 100 MW, of the cooling water if it enters the condenser at 20 C and leaves at 35 C. 2. Relevant equations 3. The attempt at a solution I thought that mass flow rate is the same all through out. I have the power and the net work but the required is mass flow rate at those given temperature. The question is from the rankine cycle.
