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)
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) = ?
