Condensation Number - Condensation Number is defined as the dimensionless number which helps us to resolve equation in terms of film Reynolds number, which is important in determining condensation behavior.
Average Heat Transfer Coefficient - (Measured in Watt per Meter² per K) - Average Heat Transfer Coefficient is equal to the heat flow (Q) across the heat-transfer surface divided by the average temperature (Δt) and the area of the heat-transfer surface (A).
Viscosity of Film - (Measured in Pascal Second) - Viscosity of Film is a measure of its resistance to deformation at a given rate.
Thermal Conductivity - (Measured in Watt per Meter per K) - Thermal Conductivity is rate of heat passes through specified material, expressed as amount of heat flows per unit time through a unit area with a temperature gradient of one degree per unit distance.
Density of Liquid Film - (Measured in Kilogram per Meter³) - Density of Liquid Film is defined as the density of the liquid film which is considered for film condensation.
Density of Vapor - (Measured in Kilogram per Meter³) - The Density of Vapor is the mass of a unit volume of a material substance.
STEP 1: Convert Input(s) to Base Unit
Average Heat Transfer Coefficient: 450 Watt per Meter² per K --> 450 Watt per Meter² per K No Conversion Required
Viscosity of Film: 0.029 Newton Second per Meter² --> 0.029 Pascal Second (Check conversion here)
Thermal Conductivity: 10.18 Watt per Meter per K --> 10.18 Watt per Meter per K No Conversion Required
Density of Liquid Film: 96 Kilogram per Meter³ --> 96 Kilogram per Meter³ No Conversion Required
Density of Vapor: 0.5 Kilogram per Meter³ --> 0.5 Kilogram per Meter³ No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Co = (h ̅)* (((μf)^2)/((k^3)*(ρf)*(ρfv)*[g])^(1/3)) --> (450)* (((0.029)^2)/((10.18^3)*(96)*(96-0.5)*[g])^(1/3))

STEP 3: Convert Result to Output's Unit
0.000829842432967196 --> No Conversion Required
FINAL ANSWER
0.000829842432967196 <-- Condensation Number
