Aclosed system at 40°c undergoes an internally reversible isothermal process in which 500 [kj] of heat energy is transferred to the surroundings a) calculate the entropy change of the system during the process. b) what must the minimum increase of entropy of the surroundings be during this process?

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.
