One pound mass of water in a piston-cylinder assembly, initially a saturated liquid at 1 atm, undergoes a constant- pressure, internally reversible expansion tox=90%. determine the work and heat transfer, each in btu. sketch the process on p-v and t-s coordinates, associate the work and heat transfer with areas on these diagrams.

Afull journal bearing has a journal diameter of 27 mm, with a unilateral tolerance of -0.028 mm. the bushing bore has a diameter of 27.028 mm and a unilateral tolerance of 0.04 mm. the l/d ratio is 0.5. the load is 1.3 kn and the journal runs at 1200 rev/min. if the average viscosity is 50 mpa-s, find the minimum film thickness, the power loss, and the side flow for the minimum clearance assembly.
