The enthalpy of the supply air is 15 Btu/lbma and the airflow is 1350 cfm. The sensible heat factor for the room is 0.80, and the enthalpy of the room air is 30 Btu/lbma. Determine the sensible and latent cooling loads for the space. Assume an inlet air specific volume at 13.5 ft3/lbm.

Air is flows through an adiabatic nozzle with an inlet pressure of 400 psia at a temperature of 300°f and a velocity of 20 ft/s. the outlet pressure is 40 psia and the velocity is 800 ftl/s. determine the outlet temperature of the air using: a) property tables b) specific heat (using the specific heat value for air at 300°f)
