Explain a pure saturated vapor and a cold surface canbe

Reference no: EM13221679

The coefficient of heat transfer between a pure saturated vapor and a cold surface canbe predicted by the following equation:
h = 0.943 [(k^3ρ ^2gλ)/ (LμΔT)]^(1/4)
where h = mean heat transfer coefficient, Btu/(hr) (ft2) (Δ°F)
k = thermal conductivity, Btu/(hr) (ft) (Δ°F)
ρ = density, lbm/ft3
g = acceleration of gravity, 4.17 × 108
λ = enthalpy change, Btu/lbm
L = length of tube, ft
μ = viscosity, lbm/(hr) (ft)
ΔT = temperature difference, Δ°F
What are the units of the constant 0.943?
