An air compressor used in a large car body shop is located in an inside equipment room. Fresh air at 5 ºC, 96 kPa is conveyed to the compressor from outside through a 30-cm circular duct that is 15-m long. The duct runs along the ceiling of the facility where the temperature is 34 ºC. If the air flow rate is 0.35 m3 /s, determine:

a. the temperature of the air when it reaches the compressor (in ºC)

b. the heat transfer rate (in W)

    A compressor is used to charge the supersonic wind tunnel air tanks at the Aerodynamics Research Center. The tanks have a total volume of 40 m3. Air is inspired at ambient pressure (101 kPa) and temperature (293 K) in a conduit with a diameter of 40 cm at an average velocity of 10 m/s. Assuming that the losses in the system are negligible, determine: (a) the rate of change of the mass of air inside the tanks; (b) the rate...

    Quantitative: In the 1950s liquid hydrogen was considered as a fuel for a new type of aircraft being developed, the SR-71 Blackbird (shown in Figure 1). Figure 1: The SR-71 Blackbird Early research on the project focused on which fuel to use for the Blackbird. Pratt & Whitney had a J-57 engine that was designed for kerosene and being considered for implementation on the Blackbird. The J-57 only took 5 months to convert to running on liquid hydrogen, however tests...
