Question 11

A rectangular flexible membrane in a water-treatment unit separates liquid at two different pressures. The pressure on one side of the membrane is 1200 Pa greater than the pressure on the other side. The membrane measures 30 cm by 25 cm.

What resultant force acts on the membrane because of the difference in liquid pressure?
