Problem 3: During summer, the temperature in Dhahran averages at 38°C for the entire day and night period. To maintain the inside of a building at the comfort level of 20°C, an Engineer suggested to use a commercial air conditioning (AC) system. The insulation and thermal design of the building is such that 28000 kJ/h of heat transfers to Inside 28000 Outside 20°C kJ/h 38°C Refrigerant loop Evaporator Condenser Compressor the building from outside. This amount of heat needs to be removed by the AC. The cost of electricity is 0.21 Ryial/kWh. Hint: 1 kWh-360OJ a. The suggested air conditioner requires a net power input to the compressor of 2 kW. Is the Engineer's suggestion valid? Calculate the coefficient of performance and the cost of electricity for one summer month. b. What is the minimum theoretical cost to operate the air conditioner? Discuss your results.

a. An air stream passing through a 2-inch (1/6 ft) diameter, thin-walled tube is to be heated by high- pressure steam condensing on the outer surface of the tube at 320 °F. The overall heat transfer coefficient, h between steam and air can be assumed to be 25 Btu/(ft2.hr °F) with the air entering at 100 ft/sec, 10 psia, 40 °F. The air is to be heated to 150 °F. Determine the tube length required. Assuming Rayleigh Line flow, calculate the static pressure change due to heat addition. Also, for the same inlet conditions, calculate the pressure drop due to friction, assuming Fanno flow in the duct with f = 0.018. b. c. d. To obtain an approximation to the overall pressure drop in this heat exchanger, add the two results. Discuss the accuracy of this calculation.
