This online tool will calculate the required mass to be added to a dead weight tester pressure calibrator by entering the target pressure, the effective area of the piston-cylinder and the local gravity.
The formula used by this calculator to determine the required mass to be added to the dead weight tester is:
F = P·A
F = m·g
m = F/g
m = P·A/g
- P = Pressure
- F = Force
- A = Area
- m = Mass
- g = Acceleration due to gravity
Target Pressure (P)
Enter the target pressure required by the dead weight tester for calibration purposes.
Effective Area (A)
Enter the effective area 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.
Required Mass (m)
This is the total mass of weights that need to be added to a dead weight tester with the specified effective area & local gravity to generate the target pressure .
