Example 21.5 Fuel oil at the rate of 1.3 kg's is heated passing through the annulus of a computer flow double pipe heat exchanger from 20°C to 30°C by using hot water available from the engine at 70°C. The water flows through a copper tube (OD-2.13 cm and ID-1.86 cm) with a velocity of 0.76 ms. The oil passes through the annulus formed by inner copper tube and outer steel pipe (OD-334cm and ID-3 cm). F. (Fouling factor water side)-0.0004 m² C/W F. (Fouling factor oil side)-0.0009 m² C/W V(m/s) Neglect the resistance of copper tube. Take the following properties of water and oil Water Of Ckj kg-C) K(W/m-C) 980 t 850 2 0.035 7.5
