Crude oil flows at the rate of 1000 kg/h through the inside pipe of a double pipe heat exchanger and is heated from 303k to 363k. the heat is supplied by kerosene initially at 473k flowing through the annular space. if the temperature of approach is (minimum temperature difference) at2 = 10k, determine the following: (i) heat transfer area for co-current flow and (7 marks) (ii) kerosene flow rate. (5 marks) data: specific heat of crude oil = 2.1 kj/(kg. k) specific heat of crude oil = 2.51 kj/(kg. k) overall heat transfer coefficient = 465 w/(m²k) the rate of heat transfer is given by: q = [ń cp at] = [m cp at]k = u. a. atim pht (chem. engg.
