Force is found by doing this to these two factors?
What is multiplying pressure and area.
This is a chemical used in taking moisture out of the air?
What is desiccant.
This type of valve in an aircraft hydraulic system permits fluid to flow freely in one direction, but restricts the rate at which fluid is allowed to flow in the other direction?
