In a 1-1 pass floating head type shell and tube heat exchanger, the tubes (od=25 mm; id=21 mm) are arranged in a square pitch. The tube pitch is 32 mm. The thermal conductivity of the shell side fluid is 0.19 W/m.K, and the Nusselt number is 200. The shell-side heat transfer coefficient (in W/m2.K), rounded off to the nearest integer, is
Correct : b
