Air is compressed in an adiabatic compressor. Inlet and outlet conditions are 120kPa, 30 oC and 20 m/s; 1.4 MPa, 530 oC and 80 m/s. The surrounding air temperature is 25 oC. The inlet cross-sectional area is 0.013 m2. Assume Cp = 1005 J/kgK, R = 287 J/kgK, k = 1.4. Enter the amount of heat loss due to irreversibility resulting from the heat transfer from the compressor in kW (correct up to one decimal place.)
Qn.4. . A 5-m-long section of an air heating system of a house passes through an unheated space in the basement. The cross section of the rectangular duct of the heating system is 20 cm x 25 cm. Hot air enters the duct at 100 kPa and 60°C at an average velocity of 5 m/s. The temperature of the air in the duct drops to 54°C as a result of heat loss to the cool space in the basement. Determine the rate of heat loss from the air in the duct to the basement under steady conditions. Also, determine the of this heat loss hour if the house is heated by a has ficiency arnac of 80 percent, and the cost of the natural gas in that area is $0.60therm (1 therm = 100,000 Btu = 105,500 kJ). Your solution must state governing equations and associated assumptions, illustration and step by sten execution of the overall solution.
