While the ideal vapor-compression cycle maintains saturated vapor at the compressor inlet, it is common to adjust the mass flow rate and the evaporator conditions to maintain a level of superheat at the compressor inlet. Why do you think this is? What side-effects might this have on the cycle?

Fluids at rest possess no flow energy. a)- true b)- false

Ajournal bearing has a journal diameter of 3.250 in with a unilateral tolerance of 20.003 in. the bushing bore has a diameter of 3.256 in and a unilateral tolerance of 0.004 in. the bushing is 2.8 in long and supports a 700-lbf load. the journal speed is 900 rev/min. find the minimum oil film thickness and the maximum film pressure for both sae 20 and sae 20w-30 lubricants, for the tightest assembly if the operating film temperature is 160°f. a computer code is appropriate for solving this problem.
