Alarge air reservoir supplies (k = 1.4 and rair = 287 n m / kg. k) a convergent nozzle that discharges at atmospheric pressure (patm = 101 kpa). assuming that the flow is reversible and adiabatic inside the nozzle, determine: if the pressure in the tank is 600 kpa (abs) and the temperature is 600k, what is the mass flow through the nozzle if the output area is 1.29x10^-3 m²?

If the thermal strain developed in polyimide film during deposition is given as 0.0044. assume room temperature is kept at 17.3 c, and thermal coefficient of expansion for the film and the substrate are 54 x 10^-6c^-1 and 3.3 x 10^-6c^-1respectively. calculate the deposition temperature.

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

Aquick transition of the operating speed of a shaft from its critical speed will whirl amplitude. (a) increase (b) limit (c) not affect (d) zero
