Dry Bulb Temperature given Vapor Density Solution

STEP 0: Pre-Calculation Summary

Formula Used

Dry Bulb Temperature = (Specific Humidity*(Total Pressure of Moist Air-Pressure of Water Vapor))/(287*Vapor Density)
t_d = (ω*(p_t-p_v))/(287*ρ_v)
This formula uses 5 Variables

Variables Used

Dry Bulb Temperature - (Measured in Kelvin) - Dry bulb temperature is the temperature of air measured by a thermometer freely exposed to the air but shielded from radiation and moisture.
Specific Humidity - Specific Humidity is the ratio of the mass of water vapor to the total mass of the air parcel.
Total Pressure of Moist Air - (Measured in Pascal) - Total Pressure of Moist Air is the pressure exerted by the mixture of air and water vapour which is equal to the sum of the respected pressures. It is also called barometric pressure.
Pressure of Water Vapor - (Measured in Pascal) - Pressure of Water Vapor is the pressure exerted by the water vapour in the moist air or the mixture of dry air and water vapour.
Vapor Density - (Measured in Kilogram per Cubic Meter) - Vapor Density is defined as the mass of water vapor present in 1 m³ of dry air. It is also called absolute humidity.

STEP 1: Convert Input(s) to Base Unit

Specific Humidity: 0.25 --> No Conversion Required
Total Pressure of Moist Air: 189 Bar --> 18900000 Pascal (Check conversion here)
Pressure of Water Vapor: 60 Bar --> 6000000 Pascal (Check conversion here)
Vapor Density: 32 Kilogram per Cubic Meter --> 32 Kilogram per Cubic Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

t_d = (ω*(p_t-p_v))/(287*ρ_v) --> (0.25*(18900000-6000000))/(287*32)

Evaluating ... ...

t_d = 351.154181184669

STEP 3: Convert Result to Output's Unit

351.154181184669 Kelvin --> No Conversion Required

FINAL ANSWER

351.154181184669 ≈ 351.1542 Kelvin <-- Dry Bulb Temperature
