Isothermal pressure-drop data for the same tube are given in terms of the dimens

Isothermal pressure-drop data for the same tube are given in terms of the dimensionless friction factor f = (?^?p/I? u2) (2D/L)gc and Reynolds number based on the pipe diameter ReD = u D/v = 4m/I?D?1 below.By comparing the isothermal with the nonisothermal friction coefficients at similar bulk Reynolds numbers derive a dimensionless equation for the non-isothermal friction coefficients in the formf = constant A?
