Question:

Jakob (1949) suggests the following correlation be used for square tubes in a liquid cross-flow situation:

Water (k = 0.61 W/m · K, Pr = 6) at 50°C flows across a 1-cm square tube with a Reynolds number of 10,000 and surface temperature of 75°C. If the tube is 2 m long, the rate of heat transfer between the tube and water is
(a) 6.0 kW

(b) 8.2 kW

(d) 15.7 kW

(e) 18.1 kW
