Hello student,

The question related to correlations for forced convection is that-

Q. The convective heat transfer coefficient in laminar flow over a flat plate;

a) Increases with distance

b) Increases if a higher viscosity fluid is used

c) Increases if a denser fluid is used

d) Decreases with increase in free stream velocity

Ans: The convective heat transfer coefficient in laminar flow over a flat plate increases if a denser fluid is used because it mostly increases if a denser fluid is used.

Hope, you get the answer.
