Consider an infinitely thin flat plate of chord c at an angle of attack α in a supersonic flow. The pressure distribution

can be approximated as follows:

i) Upper surface: Cp constant at -0.8 from the leading edge to 60% chord, then increasing linearly to +0.1 at the trailing edge.

ii) Lower surface: Cp constant at –0.4 from the leading edge to 60% chord, then increasing linearly to +0.1 at the trailing edge.

Estimate the lift coefficient and the pitching moment coefficient about the leading edge due to lift.

Refrigerant-134a enters the compressor of a refrigerator as superheated vapor at 0.14 mpa and -10°c at a rate of 0.05 ka/s and leaves at 0.8 mpa and 50°c. the refrigerant is cooied in the condenser to 0.72 mpa and 26'c. it is then throttled to 0.15 mpa. sketch the t-s diagram for the system and evaluate: 6) the rate of heat removai from the refrigerated space (kw), it) the power input to the compressor (kw), ii) the isentropic efficiency of the compressor (%), and iv) the cop of the refrigerator.
