Transcribed Image Text:Assignment 2.
Heat is transferred to 20 kg of air which is initially at 100 kPa and
300 K until its temperature reaches 600 K. Determine the
change in internal energy, the change in Enthalpy, the heat
supplied, and the wok done in the following processes:
(a). Constant Volume process
(b). Constant pressure process
Assume that air is an ideal gas for which the P-V-T relationship is
PV = nRT, where n Is the number of moles of the and R is
gas,
the ideal gas constant. R = 8.314 kJ/kmol K. Take Cp = 29.099
kJ/kmol. K, Cv = 20.785 kJ/kmol. K and molecular weight of
air = 29 mol/kg
