Air enters a horizontal, constant-diameter heating duct operating at steady state at 280 K, 1 bar, with a volumetric flow rate of 0.25 m³/s, and exits at 325 K, 0.95 bar. The flow area is 0.05 m².

Assuming the ideal gas model with k = 1.4 for the air, determine:

(a) the mass flow rate, in kg/s,

(b) the velocity at the inlet and exit, each in m/s, and

(c) the rate of heat transfer to the air, in kW
