Q.1. A refrigeration process with interstage cooling uses refrigerant HFC-134a, and the outlet of the condenser is to be saturated liquid at 40°C. Refer to the following figure for stream numbers in your solution. The pressure of the flash chamber and the intermediate pressure between compressors is to be 290 kPa. The evaporator is to operate at -20°C and the outlet is to be saturated vapor. The flowrate of stream 1 is 23 kg/h. The flash chamber may be considered adiabatic. The compressors may be considered to be 80% efficient. a) What is the power input required to the first compressor? b) What are the flowrates of streams 6 and 7? What is the enthalpy of stream 4?

Isobutane, air entering at 22 oC with a flow of 18 kg/s (cp = 1.0 kJ / kg.K)is condensed at 85 oC. The total heat transfer coefficient for this heat exchanger is 2400 W/m2.K and surface area is 2.6 m2. What is the output temperature of the air? Çeviri yap: Google Bing
Pls. Answer thank you! The evaporative condenser of an ammonia refrigeration plant has a water flow rate of 100 kg/s and enters a natural draft cooling tower at 43 °C. The water is cooled to 30 °C by air entering at 27 oC db 24 °C wet bulb. The air leaves the tower as 90% RH and 32 °C db. Calculate the percent of make-up water needed the tower. At 27 °C db and 24 °C wb: h = 72.5 KJ/kg, w = 0.0178 At 90% RH and 32 °C db: h = 102 KJ/kg, w = 0.0275
