Moist air at 20°c, 1 bar, 43% relative humidity and a volumetric flow rate of 900 m/h enters a control volume at steady state and flows along a surface, through which heat transfer occurs. liquid water at 20 °c is injected at a rate of 5 kg/h and evaporates into th flowing stream. for the control volume, wex=0, and kinetic and potential energy effects a negligible. moist air exits at 32 °c, 1 bar. determine the rate of heat transfer, in kw.
