Applying the Energy BalanceWater contained in a

QUESTION:

Water contained in a piston-cylinder assembly, initially at \(300^{\circ} \mathrm{F}\), a quality of 90%, and a volume of \(6 \mathrm{ft}^3\), is heated at constant temperature to saturated vapor. If the rate of heat transfer is \(0.3 \mathrm{Btu} / \mathrm{s}\), determine the time, in min, for this process of the water to occur. Kinetic and potential energy effects are negligible.
