Question

Convective heat transfer coefficients for liquid under forced convection is __________

(a) 0.5 – 1000 (W/(m^2K))

(b) 50 – 3000 (W/(m^2K))

(c) 10 – 1000 (W/(m^2K))

(d) 50 – 10000 (W/(m^2K))

I had been asked this question by my school principal while I was bunking the class.

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

Answer 1

The correct answer is (d) 50 – 10000 (W/(m^2K))

To explain: Explanation:  Convective heat transfer coefficients for air under natural convection is 0.5 – 1000 (W/(m^2K)).  For liquids under natural convection is 50 – 3000 (W/(m^2K)). For air under forced convection it is 10 – 1000 (W/(m^2K)). For liquids under forced convection it is 50 – 10000 (W/(m^2K)).
