Film Thickness given Mass Flow of Condensate Solution

Follow our step by step solution on how to calculate Film Thickness given Mass Flow of Condensate?

FIRST Step Consider the formula

δ = {(\frac{3 \cdot μ f \cdot ṁ}{ρ L \cdot (ρ L - ρ v) \cdot [g]})}^{\frac{1}{3}}

Next Step Substitute values of Variables

∴

δ = {(\frac{3 \cdot 0.029N*s/m² \cdot 1.4kg/s}{1000kg/m³ \cdot (1000kg/m³ - 0.5kg/m³) \cdot [g]})}^{\frac{1}{3}}

Next Step Substitute values of Constants

∴

δ = {(\frac{3 \cdot 0.029N*s/m² \cdot 1.4kg/s}{1000kg/m³ \cdot (1000kg/m³ - 0.5kg/m³) \cdot 9.8066m/s²})}^{\frac{1}{3}}

Next Step Convert Units

∴

δ = {(\frac{3 \cdot 0.029Pa*s \cdot 1.4kg/s}{1000kg/m³ \cdot (1000kg/m³ - 0.5kg/m³) \cdot 9.8066m/s²})}^{\frac{1}{3}}

Next Step Prepare to Evaluate

∴

δ = {(\frac{3 \cdot 0.029 \cdot 1.4}{1000 \cdot (1000 - 0.5) \cdot 9.8066})}^{\frac{1}{3}}

Next Step Evaluate

∴

δ = 0.00231622780848996m

LAST Step Rounding Answer

∴

δ = 0.0023m

How to Evaluate Film Thickness given Mass Flow of Condensate?

Film Thickness given Mass Flow of Condensate evaluator uses Film Thickness = ((3*Viscosity of Film*Mass Flow Rate)/(Density of Liquid*(Density of Liquid-Density of Vapor)*[g]))^(1/3) to evaluate the Film Thickness, The Film Thickness given Mass Flow of Condensate formula is defined as the function of Viscosity of film, mass flow rate of condensate, density of liquid, density of vapor. In two-phase heat transfer applications that do not contain a wick structure, a thin film of liquid is often present enclosing either partially or completely around the vapor bubbles. Film thickness would be the thickness of this thin layer of liquid. Also, there are applications that only use a thin layer of liquid for heat transfer applications. This used as it is shown to have enhanced heat transfer capabilities in certain applications. Film Thickness is denoted by δ symbol.
