Question

Determine the overall heat transfer coefficient based on outer area of a

3.81cm O.D and 3.175 cm I.D brass tube(k = 103.8 W/m K) if the heat

transfer coefficients for flow inside and outside the tubes are 2270 and

2840 W/m2

K respectively, and the unit fouling resistances at inside and

outside are Rfi = Rfo = 8.8 x 10-3 m2 K/W. full sum need no need answers​
