Nitrogen at 30?C and atmospheric pressure enter a triangular duct 0.02 m on each side at a rate of 4 x 10??4 kg/s. If the duct temperature is uniform at 200?C, estimate the bulk temperature of the nitrogen 2 m and 5 m from the inlet.GIVENAtmospheric nitrogen flowing through a triangular ductBulk inlet temperature (Tb,in) = 30?CWidth of each side of the duct (w) = 0.02 mMass flow rate (m) = 4 x 1??4 kg/sDuct temperature (Ts) = 200?C(uniform)

w =0.02 m Nitrogen Ton- 30 C m-4x 10-4 kg/s
