Problem 3 Part a P=57 Moist air enters the cooler of an air conditioning unit at 25 °C and a relative humidity of 70%. The cooled and dehumidified air leaves the cooler saturated at 18 °C. The temperature of condensed water is 18 °C. The pressure is constant at 101.325 kPa. The mass flow rate of the dry air is mda=67 kg/s. Use the psychometric chart to determine a) The humidity ratio at the...

A rectangular forced air heating duct is suspended from the ceiling of a basement whose air and walls are at a temperature of ∞T∞=Tsur= 5°C. The duct is 15 m long, and its cross section is 350 mm × 188 mm. (1) For an uninsulated duct whose average surface temperature is 50°C, estimate the rate of heat loss from the duct. The surface emissivity and convection coefficient are approximately 0.5 and 4 W/m2·K, respectively. (2) If heated air enters the...
Water entering a wet cooling tower at 35°C at a rate of 100 kg/s is cooled to 22°C in the cooling tower by air that enters the tower at 1 atm, 20°C, and 60% relative humidity and leaves saturated at 3...
Water entering a wet cooling tower at 35°C at a rate of 100 kg/s
is cooled to 22°C in the cooling tower by air that enters the tower
at 1 atm, 20°C, and 60% relative humidity and leaves saturated at
30°C. The makeup water of 22°C is supplied to the outlet to make
the mass flow rate of the cool water the same as that at the inlet,
see Figure Q5.

Problem 3: (35pts) Atmospheric air enters the heated section of a circular tube at a flow rate of 0.005 kg/s and a temperature of 30°C. The tube is of diameter D =60mm, and fully developed conditions with h = 30W/m2K exist over the entire length of L-4m. Take cp-1015 /kg.K 2 (a) (10pts) For the case of uniform surface heat flux at q"-1000W/m, determine the total heat transfer rate q and the mean temperature of the air leaving the tube...

a shell and tube heat exchanger is required to heat brine for a
food processing plant. Hot waste water from another part of the
plant is available at 90°C and a flow rate of 0.7kg/s to perform
the heating duty. An existing heat exchanger is available that has
twoshell passesand 4 tube passes. Each tube pass has a total length
of 20m and the tubes are found to be thin walled copper with a
nominal diameter of 25mm.
