Refngerant-134a is used as the working fluid in a simple ideal rankine cycle which operates the boiler at 1400 kpa and the condenser at 10 °c the mixture at the exit of the turbine has a quality of 98 percent determine a) the turbine inlet temperature, b) the cycle thermal efficiency, and c) the back-work ratio of this cycle

Slip occurs via two partial dislocations because of (a) the shorter path of the partial dislocation lines; (b) the lower energy state through partial dislocations; (c) the charge balance.

The higher the astm grain size number, the finer the gran is. a)-true b)-false

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
