Aspace is maintained at 75°f db and 50% rh. the return air has a sensible heat load of 100,000 btu/hr and a latent heat load of 40,000 btu/hr. the total outdoor air load is 80,000 btu/hr. the air supplied to the space is 55°f db and 90% rh. neglect the fan heat and heat gain from the duct system. with a temperature rise of chilled water across the cooling coil of 12°f, the rate of water flow (gpm) is most nearly: a. 15 b. 20 c c. 29 d. 35
