Problem 4.069 The figure belows shows three components of an air-conditioning system, where T3 115°F and 4.5 Ib/s. Refrigerant 134a flows through a throttling valve and a heat exchanger while air flows through a fan and the same heat exchanger. Data for steady-state operation are given on the figure. There is no significant heat transfer between any of the components and the surroundings. Kinetic and potential energy effects are negligible. Air T 535 R cp = 0.240 Btu/lb-R Saturated liquid...

Air at 95°F, 1 atm, and 10% relative humidity enters an evaporative cooler operating at steady state. The volumetric flow rate of the incoming air is 895 ft3/min. Liquid water at 68°F enters the cooler and fully evaporates. Moist air exits the cooler at 70°F, 1 atm. There is no significant heat transfer between the device and its surroundings and kinetic and potential energy effects can be neglected. a)Determine the mass flow rate of the dry air in lb(dry air)/min....

Air, modeled as an ideal gas, enters a turbine operating at steady state at 450 kPa, 800 K and exits at 100 kPa. The temperature of the exiting air is 420 K. a) If the turbine is well insulated and you can ignore kinetic and potential energy effects, determine if the exit temperature can be correct. b) What if the exit temperature is 550 K? Explain you’re your reasoning. Hint: Find the entropy generation rate first.
