A pneumatic motor in a highly explosive environment uses a mixture of the ideal gases argon and helium in equal parts on a mass basis. The motor has inlet conditions of 150. psia at 500. R and an exit pressure of 14.7 psia. If the motor must produce 3.00 hp of output power while operating in a steady state, steady flow, reversible, and adiabatic manner, then
a. What is the exit temperature of the gas mixture?
b. What mass flow rate of the mixture is required?
