Density From Pressure Formula
The following formula is used to calculate the Density From Pressure.
Dp = P / (R*T)
- Where Dp is the Density From Pressure (kg/m^3)
- P is the pressure (Pa)
- T is the temperature (K)
- R is the universal gas constant (8.314)
To calculate density from pressure, divide the pressure by the product of the temperature and the gas constant.
How to Calculate Density From Pressure?
The following example problems outline how to calculate Density From Pressure.
Example Problem #1:
- First, determine the pressure (Pa).
- The pressure (Pa) is given as: 600.
- Next, determine the temperature (K).
- The temperature (K) is provided as: 100.
- Finally, calculate the Density From Pressure using the equation above:
Dp = P / (R*T)
The values given above are inserted into the equation below:
Dp =600/ (8.314*100) = .721 (kg/m^3)
Example Problem #2:
For this problem, the variables needed are provided below:
pressure (Pa) = 159
temperature (K) = 134
This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer.
Dp = P / (R*T) = ?
