Consider a flat plate of width 0.6 m and length 1.3 m that is maintained at a temperature of 40◦c. water at 20◦c flows across the top of the plate in parallel flow at a velocity of 3 m/s. determine the rate of convection heat transfer and drag force on the plate. what if the flow was fully turbulent over the plate?

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.
