Considering the variability of the specific heats of air, plot the change in specific enthalpy of air as it is heated from an initial temperature of 0°C to final temperatures ranging from 100°C to 1000°C.
Given: T1 = 0°C
What will be an ideal response?
For an ideal gas with variable specific heats. ?h = h2 – h1 .
The values for the specific enthalpy can be found on-line or from air tables at specific
temperatures.
h1 = 273.11 kJ/kg
Plotting the change in specific enthalpy yields
