Air at 3.5 MPa and 38oC flows across a tube bank consisting of 400 tubes of 1.25-cm

Question:

Air at 3.5 MPa and 38oC flows across a tube bank consisting of 400 tubes of 1.25-cm OD arranged in a staggered manner 20 rows high; Sp = 3.75 cm and Sn = 2.5 cm. The incoming-flow velocity is 9 m/s, and the tube-wall temperatures are maintained constant at 20oC by a condensing vapor on the inside of the tubes. The length of the tubes is 1.5 m. Estimate the exit air temperature as it leaves the tube bank.
