Dew Point Depression Solution

STEP 0: Pre-Calculation Summary

Formula Used

Dewpoint Depression = Temperature-Dewpoint Temperature
dpd = T-dpt
This formula uses 3 Variables

Variables Used

Dewpoint Depression - (Measured in Kelvin) - Dewpoint Depression is the difference between the temperature and dew point temperature at a certain height in the atmosphere.
Temperature - (Measured in Kelvin) - Temperature is the degree or intensity of heat present in a substance or object.
Dewpoint Temperature - (Measured in Kelvin) - Dewpoint Temperature is defined as the temperature to which the air would have to cool (at constant pressure and constant water vapor content) in order to reach saturation.

STEP 1: Convert Input(s) to Base Unit

Temperature: 85 Kelvin --> 85 Kelvin No Conversion Required
Dewpoint Temperature: 100 Kelvin --> 100 Kelvin No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

dpd = T-dpt --> 85-100

Evaluating ... ...

dpd = -15

STEP 3: Convert Result to Output's Unit

-15 Kelvin --> No Conversion Required

FINAL ANSWER

-15 Kelvin <-- Dewpoint Depression

Density of Two Liquids

Go Density of Two Liquids = (Mass of Liquid A+Mass of Liquid B)/(Mass of Liquid A/Density of Liquid A+Mass of Liquid B/Density of Liquid B)

Specific Humidity

Go Specific Humidity = 0.622*Relative Humidity*Vapor Pressure of Pure Component A/(Partial Pressure-Relative Humidity*Vapor Pressure of Pure Component A)

Spring Work

Go Spring work = Spring Constant*(Displacement at point 2^2-Displacement at point 1^2)/2

Shaft Power

Go Shaft Power = 2*pi*Revolutions per Second*Torque Exerted on Wheel

Refrigerator Work

Go Refrigerator Work = Heat from High Temperature Reservoir-Heat from Low Temperature Reservoir

Vapour Quality

Go Vapour Quality = Vapour Mass/(Vapour Mass+Fluid mass)

Real Refrigerator

Go Real Refrigerator = Heat from Low Temperature Reservoir/Work

Dew Point Depression

Go Dewpoint Depression = Temperature-Dewpoint Temperature

Degree of Saturation

Go Degree of Saturation = Volume of Water/Volume of Voids

Water Equivalent

Go Water equivalent = Mass of Water*Specific Heat

Relative Density

Go Relative Density = Density/Water Density

Dew Point Depression Formula

Dewpoint Depression = Temperature-Dewpoint Temperature
dpd = T-dpt
