A tank of 20 ft3 volume is half-filled with liquid water, and the remainder is filled by vapor at 550 psia. The water is heated until one-half of the liquid (by volume) is evaporated, while an automatic valve lets saturated vapor escape at such a rate that the pressure is held constant at 550 psia.

Determine the heat transfer during the process.

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

The drive force for diffusion is 7 fick's first law can be used to solve the non-steady state diffusion. 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
