Question: b ) A gas enters an adiabatic work consuming device at 3 0 0 K , 2 0 m s , and leaves at 5

)

A gas enters an adiabatic work consuming device at

300 K, 20 \frac{m}{s},

and leaves at

500 K, 40 \frac{m}{s}

as shown in Figure

2 .

If the mass flow rate is

5 k \frac{g}{s},

determine the rate of work transfer. Neglect changes in potential energy and assume the specific enthalpy of the gas to be related to its temperature in K through

h = 1.005 T .
