Two nonconducting tanks of negligible heat capacity and of equal volume initiallycontain
Chapter 7, Problem 7.14(choose chapter or problem)
Two nonconducting tanks of negligible heat capacity and of equal volume initiallycontain equal quantities of the same ideal gas at the same T and P. Tank A dischargesto the atmosphere through a small turbine in which the gas expands isentropically;tank B discharges to the atmosphere through a porous plug. Both devices operate untildischarge ceases.(a) When discharge ceases, is the temperature in tank A less than, equal to, or greaterthan the temperature in tank B?(b) When the pressures in both tanks have fallen to half the initial pressure, is thetemperature of the gas discharging from the turbine less than, equal to, or greaterthan the temperature of the gas discharging from the porous plug?(c) During the discharge process, is the temperature of the gas leaving the turbine lessthan, equal to, or greater than the temperature of the gas leaving tank A at the same
instant?
(d) During the discharge process, is the temperature of the gas leaving the porous plug
less than, equal to, or greater than the temperature of the gas leaving tank B at the
same instant?
(e) When discharge ceases, is the mass of gas remaining in tank A less than, equal to,
or greater than the mass of gas remaining in tank B?
