V LIS An air conditioning system of an indoor ice skating rink processes V = 400.0 L/s of air. The air inlet is at Ti = 25 C, P1 = 1 atm, and has a relative humidity of rh = 93.0% (it is a very humid day). The air conditioner's outlet expels air at Tz = 0.01 C and P2 = 1 atm. You would like to determine how much water has condensed from the air and the rate of heat removed from the air. Follow these steps. n, mol air/s TC P, = 1 atm rh % y mol water/mol air Vida mol dry air/mol air Air conditioning n, mol air/s unit TC P = 1 atm you mol water/mol air yspa mol dry air/mol air n mol liquid water/s T, = 0.01 C What is the flow rate of air into the AC unit? 4.08528 ni = mol/s Incorrect What is the flow rate of water vapor into the AC unit? 0.1205 niw = mol H, O(g)/s Incorrect What is the flow rate of dry air into the AC unit? 3.96478 NIDA = mol D.A./S Incorrect What is the flow rate of dry air out of the AC unit? 3.96478 n3DA = mol D.A./s Incorrect What is the flow rate of water vapor out of the AC unit? 0.0158 n3w = mol H, O(g)/s Incorrect What is the flow rate of water condensing out of the AC unit? 0.1047 n2 = mol H, 0(1)/s Incorrect In the remaining questions, use for air a reference state of air at 25 C and 1 atm and for water a reference state of liquid water at 0.01 C. Assume that changes in enthalpy due to pressure are insignificant. What is IDA, the specific enthalpy of air at 25 C?
