When an incompressible, inviscid fluid flows against a flat plate in a two-dimensional flow, the steady velocity field is with A>0. The point (0,0) is the stagnation point where the flow divides and the velocity is zero. Plot the streamlines in this flow for the region y>0, -3

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.
