At what rate must heat be supplied to 15.0 kg/s of air, if the temperature is increased from 61.0°C to 650°C?
a) Calculate the rate that heat must be supplied by integrating the heat capacity formula for air.
b) Calculate the rate that heat must be supplied using the specific enthalpy table of gases located in your text by following the steps below. What is the specific enthalpy of air at 61.0°C, if the reference state is pref = 1 atm, and Tref = 25°C? Use the specific enthalpy table of gases in your text for this calculation.
c) What is the specific enthalpy of air at 650°C, if the reference state is pref = 1 atm, and Tref = 25°C. Use the specific enthalpy table of gases in your text for this calculation.
d) Calculate the rate that heat must be supplied to 15.0 kg/s or air.
