1. . Calculate the heat transfer area in shell-and-tube counter-current heat exchanger with diameter D - 550 mm, length L 1000 mm and quantity - 400 tubes with diameter du/dw25/21 mm each. The team conduction coefficient of the tube material 2-380 W/mK Water is heated with the aid of condensing steam. The water flowing between shell and tubes space. Temperature at the Inlet to the heat exchanger 1 = 12C. and on the outlet to -58C. Data for waterp993.3 kg/ m.7.273 10* Pas.c-4199,361/68K, 2-0.626 w/mk The steam flows in tubes. Condensation temperature te-102C. Condensate quantity m = 160 kg/h. The heat of condensation r = 2257 kJ/kg. Heat transfer coefficient for the condensing steam a = 9500 W/mK. of 50 bras Step by Step Solution
