Required information Problem 05.088 - Mixing process An air-conditioning system involves the mixing of cold air and warm outdoor air before the mixture is routed to the conditioned room in steady operation. Cold air enters the mixing chamber at 7°C and 105 kPa at a rate of 0.570 m³/s while warm air enters at 34°C and 105 kPa. The air leaves the room at 24°C. The ratio of the mass flow rates of the hot to cold airstreams is 1.6. The gas constant of air is R 0.287 kPa - m³/kg- K. The enthalpies of air are obtained from air 307.23 kJ/kg, and hroom 297. 18 kJ/kg. Use data from the steam table. table h₁ = 280. 13 kJ/kg, h₂ = 3 Cold air 7°C Warm air 34°C Room 24°C Problem 05.088.b Mixing process Determine the rate of heat gain of the room. The rate of heat gain of the room is kW. (Round the final answer to three decimal places.)
