Document Summary
Phys 101: physics for the life sciences lecture 32: Take a and b to be two different levels of a fluid. A is higher than b by an amount y. Then the pressure at b is : A car lift in a service station uses compressed air to exert a force on a small cylinder with radius 5-cm. This pressure will be transmitted by a fluid to a piston of radius 15-cm. Note: the two pistons are at the same height. Since the two pistons are at the same height the pressure at the two pistons is the same. 9 (the force exerted on piston 1 is 1/9 the weight force of the car) Sometimes pressure is quoted in mm hg. This is the upward force exerted on a body that is submerged or partially submerged in a fluid. Consider a bucket full of a fluid and a cube of height h inside the bucket.
