=+6-17. Suppose a space has a sensible heat loss of 100,000 Btu/hr (29 kW) but has a latent heat gain of 133,000 Btu/hr (39 kW). Air to ventilate the space is heated from 55 F (13 C), 35 percent relative humidity to the required state for supply to the space. The space is to be maintained al 75 F (24 C) and 50 percent relative humidity. How much air must be supplied to satisfy the load condition, in cfm (m /s)?
