Hello, please use IP unit thank you.

There are 25 students working in CCE computer lab in Owen 241. 1) What is the amount of sensible heat (in Btu) generated from students in each hour? Assume the average heat release rate from each person is 55W. Use a conversion factor, 1W=3.41Btu/h. 2) What is the amount of latent heat (in Btu) generated from students in each hour? Assume an average person dissipates latent heat at a minimum rate of 40W while doing light work such as working with computer. 3) What is the total occupant load of this classroom? 4) What is the amount of water the HVAC system should extract from this classroom per hour to maintain the relative humidity of this space at 22C ? Hint: use L=hfgmw The enthalpy of vaporization of water (hfg) at 22C is 2449.4kJ/kg. 5) We want to keep the temperature of this classroom at 22C. Assuming that students are the only heat source in this room, how much air (in ft3 ) at 18C per hour should the supply air diffusers deliver to the room to maintain the room temperature at 22C ? Assume =1.2041m3kg and Cp=1.006kgKkJ
