A local shop is maintained at 101.3 kPa and 19oC. The air inside the shop is forced to leave at a rate of 150 m3/h as a result of outdoor air at 8oC infiltrating into the shop through the cracks. Determine the rate of net energy loss of the shop due to mass transfer. The gas constant of air is R = 0.287 kPa•m3/kg•K
