Apiston-cylinder with a volume of 0.20 m3 holds 1 kg of h20 at a pressure of 150 kpa. transfer of heat to the cylinder causes an isothermal expansion of the piston until the volume quadruples. a. find the heat transferred during this process (kj) b. find the work done during this process (kj).

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.
