
Pump out the air between the plates.

The force acting on the Magdeburg plates can be
determined by the equation Force = Pressure x
Area. It should be noted that some residual air
remains between the plates that acts against the
atmospheric pressure. This should be considered
when calculating the force:
Force = (Atmospheric pressure – Residual pressure)
x Area

Use the pressure sensor to work out the pressure
due to the residual air between the plates.

Measure the atmospheric pressure using a barom-
eter.

Calculate the area in m
the ring.

Perform your calculations.

Repeat the experiment using the second sealing
ring and compare the results.
