This online tool will calculate the pressure generated by a dead weight tester pressure calibrator by entering the total mass of added weights, the effective area of the piston-cylinder and the local gravity.
The formula used by this calculator to determine the pressure generated by the dead weight tester is:
F = m·g
P = F/A
P = m·g/A
- P = Pressure
- F = Force
- A = Area
- m = Mass
- g = Acceleration due to gravity
Mass of Dead Weights (m)
Enter the total mass of weights added to the dead weight tester.
Effective Area (A)
Enter the effective area of the dead weight tester, which you should find in the manufacturer’s documentation or instrument labelling.
Local Gravity (g)
Enter the acceleration due to gravity for your geographical location in metres per second per second (ms-2). The local gravity is dependent on several factors such as latitude, height above sea-level, local geological density, etc… Refer to your national geological survey data for your location or use this local gravity calculator to determine a close approximation. The default value is set to 9.80665 ms-2 which is standard gravity.
Generated Pressure (P)
This is the pressure produced by a dead weight tester with the entered quantities for mass, area and gravity.
