Acarnot engine operates between a high temperature of th and a low temperature of tl=280k using one mole of an ideal monatomic gas as a working fluid. the initial pressure is 1.00x105 pa and the initial volume is v1= 0.0248 m3. during the isothermal expansion the volume increases to v2= 0.050m3. calculate the volume v3 at the conslusion of the adiabatic expansion.

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.
