Air is containted in a spring loaded piston cylinder device. The volume and pressue of the air at e initially 5m^3 and 300 kpa, respectively. Air i is expanded until its volume and pressure reach 4m^3 and 50 kPa, respectively.

a. Sketch this process on a P-V diagram.
b. Calculate the boundary work Wb

Line joining liquid phase with liquid and solid phase mixture is known as: a) liquidus b) solidus c) tie line d) none of the mentioned

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature

Condition monitoring is a major component of. (clo4) a)- predictive maintenance. b)-preventive maintenance c)-proactive maintenance d)-reactive maintenance.
