WebFeb 2, 2011 · The Nusselt number Nu = αl/λf or the Stanton number St = is used as a dimensionless number for heat transfer in these equations, where 1 is the characteristic dimension of the surface in the flow, the mass velocity of the fluid flow, λ f and C pf the fluid thermal conductivity and heat capacity. Webwhere. Q = heat transfer rate, W=J/s [btu/hr] A = heat transfer surface area, m 2 [ft 2] U = overall heat transfer coefficient, W/ (m 2 °C) [Btu/ (hr-ft 2 °F)] ΔTLM = logarithmic mean temperature difference, °C [°F] From this equation it can be seen that the U value is directly proportional to Q, the heat transfer rate.
