Question: What is a good approximation for the heat transfer coefficient of hydrocarbons inside 3/4" tubes?
Keywords: shell,tube,heat,transfer,coefficients,estimating,coefficients,hydrocarbon,3//4",tubes
Answer: 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-0FViscosity (cP)This is limited to a maximum viscosity of 3 cP Source: Gulley Computer Associates
