Question

how to calculate pressure of piston of two cylendrical vessel A & B with area 8cm^2 & 320cm^2 respectively

Answer 1

The formula for pressure is:
\[P=\frac F A\]
F is the force and A is the area its applied to.
So the pressure on the cylinder with 8cm2 should be:
\[P= \frac F {8\times 10^{-4}}=1.25\times10^3F\]
If F is measured in Newtons, the pressure is in Pascal units of pressure.
And the second one:
\[P= \frac F {3.2\times 10^{-2}}\]
