A gas enters an adiabatic work consuming device at 300 K, 20 m/s, and leaves at 500 K, 40 m/s.
(a) If the mass flow rate is 5 kg/s, determine the rate of work transfer. Neglect change in potential energy and assume the specific enthalpy of the gas to be related to its temperature in K through h = 1.005T.
(b) What-if Scenario: By what percent would the answer change if the change in kinetic energy were also neglected?
