Solved: Applying the Energy BalanceA piston-cylinder
Chapter 3, Problem 57P(choose chapter or problem)
A piston-cylinder assembly contains water, initially saturated liquid at \(150^{\circ} \mathrm{C}\). The water is heated at constant temperature to saturated vapor.
(a) If the rate of heat transfer to the water is \(2.28 \mathrm{~kW}\), determine the rate at which work is done by the water on the piston, in kW.
(b) If in addition to the heat transfer rate given in part (a) the total mass of water is \(0.1 \mathrm{~kg}\), determine the time, in s, required to execute the process.
