A1-m by 1-m vertical plate is exposed to saturated water vapor at 1 atm. if the surface of the plate is maintained at 20°c and the mass flow rate of the film is 1 kg/s (use the following property for saturated liquid water60°c and 1 atm: 4.63 x 104 kg/m-s), the flow condition is (a) turbid (b) transition (c) laminar (d) turbulent

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.
