Bar and vety large storage tank contains nitrogen gas maintained at degrees celcius. it is connected by a valve to a small tank. tank b is fitted with an outlet valve. both valves c and d are initially closed and tank b in itally contains nitrogen gas at 1 atm and degrees celcius. valve c is opened and nitrogen is allowed to flow from a to b until the pressures in the two tanks equalize. valve c is then closed and valve d is opened to blow down tank b to its original pressure(1 atm). this sequence is repeated a number of times. assume tank a to be so large that there is no significant drop in nitrogen pressure of 7.5 bar. also assume that there is no heat transfer between the tanks and the surroundings. nitrogen is an ideal gas with cp = 29.33 j/mol k.
(a) calculate the temperature of the gas in b after the second pressurization and after the second blow down.
(b) estimate these temperatures after completing a very large number of cycles.
