If pressure inside a cylinder with a circular hatch is 2.0 atm and the radius of the entrance hatch is 18.0 inches, what force (in lbs) does the air exert on the hatch? Recall that the area of a circle is ??r²

Step 1
Given that the radius \(r = 18.0\) inches, we have: \(A = \pi \times 18.0^2 = 1017.876\) square inches. Show more…

A 20 -cm-diameter circular cover is placed over a $10-\mathrm{cm}-$ diameter hole that leads into an evacuated chamber. The pressure in the chamber is $20 \mathrm{kPa}$. How much force is required to pull the cover off?
A vertical cylindrical tank contains 1.80 $\mathrm{mol}$ of an ideal gas under a pressure of 1.00 atm at $20.0^{\circ} \mathrm{C}$ . The round part of the tank has a radius of $10.0 \mathrm{cm},$ and the gas is supporting a piston that can move up and down in the cylinder without friction. (a) What is the mass of this piston? (b) How tall is the column of gas that is supporting the piston?
