Variables Used
Constant B - Constant B is the number that has a fixed value in a given situation or universally or that is characteristic of some substance or instrument.
Net Evaporation Losses - Net Evaporation Losses from Reservoirs on the Stream is the loss of stored volatile liquid component or mixture by evaporation by temperature, pressure, and vapor-recovery systems.
Atmospheric pressure - (Measured in Pascal) - Atmospheric pressure also known as barometric pressure (after the barometer), is the pressure within the atmosphere of Earth.
Mean Wind Velocity - (Measured in Meter per Second) - Mean Wind Velocity is the average velocity of the wind at certain height.
Maximum Vapour Pressure - (Measured in Pascal) - Maximum Vapour Pressure is the maximum value of pressure applied by the vapours.
Actual Vapour Pressure - (Measured in Pascal) - Actual Vapour Pressure is the value of pressure applied by the vapours.
STEP 1: Convert Input(s) to Base Unit
Net Evaporation Losses: 2 --> No Conversion Required
Atmospheric pressure: 198.9 Pascal --> 198.9 Pascal No Conversion Required
Mean Wind Velocity: 2 Centimeter per Second --> 0.02 Meter per Second (Check conversion here)
Maximum Vapour Pressure: 2 Centimeter Mercury (0 °C) --> 2666.44 Pascal (Check conversion here)
