Question

Convective heat transfer coefficients for condensing water vapor is __________

(a) 0.5 – 1000 (W/(m^2K))

(b) 5 – 100 (W/(m^2K))

(c) 10 – 1000 (W/(m^2K))

(d) 50 – 10000 (W/(m^2K))

I had been asked this question in examination.

The doubt is from Heat Convection topic in division Heat Transfer Theory of Food Processing Unit Operations

Answer 1

Right answer is (b) 5 – 100 (W/(m^2K))

Easiest explanation: A convective heat transfer coefficient for condensing water vapor is 5 – 100 (W/ (m^2K)). It is proportionality constant between heat flux and temperature difference that plays an important factor as driving force for the flow of heat.
