Asystem executes a power cycle while receiving 900 btu by heat transfer at a temperature of 900°r and discharging 800 btu by heat transfer at a temperature of 540°r. there are no other heat transfers. determine the cycle thermal efficiency. use the clausius inequality to determine σcycle, in btu/°r. determine if this cycle is internally reversible, irreversible, or impossible

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

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.
