Question 18
XE-GNAT2 marksNeeds review
Fruit juice was cooled in a tubular heat exchanger from 50 °C to 7 °C using water at 2 °C, which gets heated to 5 °C. Assume, Pr = 0.72, Re = 2000 and thermal conductivity = 0.6 W m⁻¹ °C⁻¹ and no viscous effect. If pipe diameter was 10 cm, the convective heat transfer coefficient (W m⁻² °C⁻¹) is ________ (round off to 1 decimal place).
