Homework Help: Please Help Me With This Question

  1. Dec 11, 2007 #1
    I have tried and tried to figure this out but i'm getting no where. Can anyone help me?

    (a) Calculate the gauge pressure (it does not include atmosphereric P) required to compress pure water from 1.000 L to 989 mL. Give an answer in both N/m^2 and psi, lb/in^2.

    (b) What height in meters and feet of a 1x1 cm^2 steel bar (density=7.86 g/cm^3) is required to exert the pressure found in part (a)?

    (c) How many total pounds of steel would be required to exert this pressure on one cubic face of a liter of water (1 L= 1 cubic decimeter)?

    The answer has to do with the compressibility of water. Look that up. Then start the problem and if you have a problem, post a more specific question.
