Homework Help: Pressure response

  1. Jul 18, 2006 #1
    If we had a tube 1 foot long that had two pistons inside it at each end of the tube, Piston #1. and Piston #2. Piston #1. is attached to a hydrolic push Rod, Piston #2. is connected to a movement senser only, the Space between the two Pistons inside the Tube have a Vacuum of 1 Torr between them, Here's the Question, If Piston #1. is actuated in or out what would be the response time that Piston #2. senses movement for both in and out actuation of Piston #1 due to pressure changes caused by the actuation of Piston #1?

    What would be your initial guess, and why? You need to show some work of your own in order for us to provide some help.

    Could it be calculated from the speed of sound? Wouldnt that require also the diameter of the tube?
