. As shown in the Figure, a system undergoing a power cycle develops a net power
output of 1 MW while receiving energy by heat transfer from steam condensing from saturated
vapor to saturated liquid at a pressure of 100 kPa. Energy is discharged from the cycle by heat
transfer to a nearby lake at . These are the only significant heat transfers. Kinetic and potential
energy effects can be ignored. For operation at steady state, determine the minimum theoretical
steam mass flow rate, in kg/s, required by any such cycle
