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)
