Reynolds Number using Average Heat Transfer Coefficient for Condensate Film Solution

STEP 0: Pre-Calculation Summary
Formula Used
Reynolds Number of Film = ((4*Average Heat Transfer Coefficient*Length of Plate* (Saturated Temperature-Temperature of Plate))/ (Latent Heat of Vaporization*Viscosity of Film))

This formula uses 6 Variables
Variables Used
Average Heat Transfer Coefficient - 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). (Measured in Watt per Meter² per K)
Length of Plate - Length of Plate is the distance between two extreme points along one side of the base plate. (Measured in Meter)
Saturated Temperature - Saturated temperature is the temperature at which a given liquid and its vapour or a given solid and its vapour can co-exist in equilibrium, at a given pressure. (Measured in Celsius)
Temperature of Plate - Temperature of Plate is the temperature at which vapor is condensing on the plate. (Measured in Kelvin)
Latent Heat of Vaporization - The Latent Heat of Vaporization is defined as the heat required to change one mole of liquid at its boiling point under standard atmospheric pressure. (Measured in Joule per Kilogram)
Viscosity of Film - Viscosity of Film is a measure of its resistance to deformation at a given rate. (Measured in Newton Second per Meter²)
