Air is heated from 50 f to 200 f in a rigid container with a heat transfer of 500 btu. assume that the air behaves as an ideal gas. determine the volume of air [ft3] if the initial pressure is 2 atm. also show the process on a p-v state diagram. use the following temperature conversion: t[r] = t[f] + 460.

Abrayton cycle operates with a regenerator on the air-standard with properties evaluated at 400 k. the tem- perature of the air entering the compressor is 350k while the temperature of the air exiting the compressor is 600 k. the temperature of the air entering the turbine is 1600 k. the overall cycle produced 600 kj/kg of net work out. assuming a regenerator effectiveness of 0.8, what is the temperature of the air before heat addition (combustion)? draw this process on a t - s diagram

Steam enters a converging-diverging nozzle at 1.0 mpa and 500°c with a negligible velocity at a mass flow rate of 2.5 kg/s, and it exits at a pressure of 200 kpa. assuming the flow through the nozzle to be isentropic, determine: the exit area and (a) (b) the exit mach number

Acylindrical tank is capable of storing 20,000 foot-pounds [ft ibf] of energy for use in your roommate's 2006 subaru wrx. the tank contains nitrous oxide, n20, which you may assume is an ideal gas and has a molecular weight of 44 grams per mole 1g/mol. the tank fits in a space in the trunk that is no wider than 6 inches fin] and no longer than 10 inches [inj, and you may assume the warm clemson weather is keeping the temperature of the tank inside the trunk at a constant 100 degrees fahrenheit [°fl. what is the weight of the nitrous oxide occupying the tank when full, in units of dynes
