Chemical Engineering Interview Question:

What is a good approximation for the heat transfer coefficient of hydrocarbons inside 3/4" tubes?

Submitted by: Administrator

Use the following equation to estimate the heat transfer coefficient when liquid is flowing inside 3/4 inch tubing: Hio = 150./sqrt(avg. viscosity) Where: Hio (BTU/ft2-hr-0F Viscosity (cP) this is limited to a maximum viscosity of 3 cP
