4. In 1916, Nusselt derived a theoretical relation for predicting the coefficient of heat transfer between a pure saturated vapor and a colder surface: 1/4 h = 0.943 k³p²gX LUAT BTU where h is the mean heat transfer coefficient (h[=] (hr))(0F)), k is the thermal conductivity (k[=] 5), ), p is the density (p[=] #1), 9 is acceleration due to gravity (g[-] 4.17 x 108), A is the enthalpy change of evaporation (A[=] BTU), BTU (hr) (ft)(°F)
