Variables Used

Reynolds Number of Film - Reynolds Number of Film is the ratio of Inertial force to the viscous force.
Average Heat Transfer Coefficient - (Measured in Watt per Square Meter per Kelvin) - 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).
Length of Plate - (Measured in Meter) - Length of Plate is the distance between two extreme points along one side of the base plate.
Saturation Temperature - (Measured in Kelvin) - Saturation 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.
Plate Surface Temperature - (Measured in Kelvin) - Plate Surface Temperature is the temperature at the surface of the plate.
Latent Heat of Vaporization - (Measured in Joule per Kilogram) - Latent Heat of Vaporization is defined as the heat required to change one mole of liquid at its boiling point under standard atmospheric pressure.
Viscosity of Film - (Measured in Pascal Second) - Viscosity of Film is a measure of its resistance to deformation at a given rate.

STEP 1: Convert Input(s) to Base Unit

Average Heat Transfer Coefficient: 115 Watt per Square Meter per Kelvin --> 115 Watt per Square Meter per Kelvin No Conversion Required
Length of Plate: 65 Meter --> 65 Meter No Conversion Required
Saturation Temperature: 373 Kelvin --> 373 Kelvin No Conversion Required
Plate Surface Temperature: 82 Kelvin --> 82 Kelvin No Conversion Required
Latent Heat of Vaporization: 2260000 Joule per Kilogram --> 2260000 Joule per Kilogram No Conversion Required
Viscosity of Film: 0.029 Newton Second per Square Meter --> 0.029 Pascal Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Re_f = ((4*h ̅*L*(T_Sat-T_w))/(h_fg*μ_f)) --> ((4*115*65*(373-82))/(2260000*0.029))

Evaluating ... ...
