2. Air is heated while flowing through a duct with a heat input of 1200 W and flow rate of 0.04 m3/s. For an inlet condition of 23°C and 1 atm, determine the theoretical increase in: (a) the thermal energy of the fluid, (b) the mechanical energy of the fluid, (c) the enthalpy of the fluid, and (d) the temperature of the fluid. 2.
