7-112 Air is to be heated by passing it over a bank of 3-m-long tubes inside which steam is condensing at 100°C. Air approaches the tube bank in the normal direction at 20°C and 1 atm with a mean velocity of 5.2 m/s. The outer diameter of the tubes is 1.6 cm, and the tubes are staggered with longitudinal and transverse pitches of SL = ST = 4 cm. There are 20 rows in the flow direction with 10 tubes in each row. Determine (a) the rate of heat transfer, (b) the pressure drop across the tube bank, and (c) the rate of condensation of steam inside the tubes. Evaluate the air properties at an assumed mean temperature of 35°C and 1 atm. Is this a good assumption? 7-113 Repeat L Prob. 7-112 for in-line arrangement with SL = ST = 6 cm.

answer PROBLEM 7-113

7-112 Air is to be heated by passing it over a bank of 3-m-long tubes inside which steam is condensing at 100°C. Air approaches the tube bank in the normal direction at 20°C and 1 atm with a mean velocity of 5.2 m/s. The outer diameter of the tubes is 1.6 cm, and the tubes are staggered with longitudinal and transverse pitches of SL = ST = 4 cm. There are 20 rows in the flow direction with 10 tubes in each row. Determine (a) the rate of heat transfer, (b) the pressure drop across the tube bank, and (c) the rate of condensation of steam inside the tubes. Evaluate the air properties at an assumed mean temperature of 35°C and 1 atm. Is this a good assumption? 7-113 Repeat G Prob. 7–112 for in-line arrangement with SL = ST = 6 cm.
