Question details

Q3) Air at 3.5 MPa and 38°C flows across a tube bank consisting of 400 tubes of 1.25- cm OD arranged in a staggered manner 20 rows high; SL= 3.75 cm and ST= 2.5 cm. The incoming flow velocity is 9 m/s, and the tube wall temperatures are maintained constant at 200°C by a condensing vapor on the inside of the tubes. The length of the tubes is 1.5m a) Estimate the exit air temperature as it leaves the tube bank b) Find the pressure drop (AP) through the tube bank
