At steady state, moist air at 298C, 1 bar, and 50%

Chapter 12, Problem 12.65

(choose chapter or problem)

At steady state, moist air at \(29^{\circ} \mathrm{C}\), 1 bar, and 50% relative humidity enters a device with a volumetric flow rate of \(13 \mathrm{m}^{3} / \mathrm{s}\). Liquid water at \(40^{\circ} \mathrm{C}\) is sprayed into the moist air with a mass flow rate of 22 kg/s. The liquid water that does not evaporate into the moist air stream is drained and flows to another device at \(26^{\circ} \mathrm{C}\) with a mass flow rate of 21.55 kg/s. A single moist air stream exits at 1 bar. Determine the temperature and relative humidity of the moist air stream exiting. Ignore heat transfer between the device and its surroundings and kinetic and potential energy effects.
