| Exhaust gases are used to prehea! waler laxing inside the tubes of a lube bank made of 14 rows (along the flow of gases), 19 tubes each, and arranged inline with longinal and transverse pics of Som each The tubes are 50 cm long with inter and oute diameters of 18 cmn and 2.1 cm, respectively. Exhaust gases enter the tube bank an al direction with a velocity of 45 ms and a temperature of 277'C. The we enters the tubes at 220 and a lotal flowrale of 6 kg's, snd captures a heat of 1200m from the gases. Using the properties of air for exhaust gases, determine the exit temperatures of both gast's and water and the average temperature of the tabe walls. WRIST
