Enter the total pressure (Pa) and the change in volume (m^3) into the calculator to determine the Work From Pressure and Volume.

## Work From Pressure and Volume Formula

The following formula is used to calculate the Work From Pressure and Volume.

W = -p*dV

• Where W is the Work From Pressure and Volume (Joules)
• p is the total pressure (Pa)
• dV is the change in volume (m^3)

## How to Calculate Work From Pressure and Volume?

The following two example problems outline how to calculate the Work From Pressure and Volume.

Example Problem #1:

1. First, determine the total pressure (Pa). In this example, the total pressure (Pa) is given as 50.
2. Next, determine the change in volume (m^3). For this problem, the change in volume (m^3) is given as 30.
3. Finally, calculate the Work From Pressure and Volume using the equation above:

W = -p*dV

Inserting the values from above and solving the equation with the imputed values gives:

W = -50*30 = -1500 (Joules)

Example Problem #2:

Using the same process as above, first define the variables required by the formula. In this case, these values are:

total pressure (Pa) = 100

change in volume (m^3) = 25

Entering these values yields:

W = -100*25 = -2500 (Joules)
