Homework Help: Bernoulli Problem

  1. Jan 15, 2012 #1
    hi

    i want to check if i have done this the right way as their are two density values given.
    i used bernoulli's equation for incompressable fluid flow.

    V^2 = 2(p1-p2)/air density = 0.166 meters/s

    is it correct to use the air density in this way even though the manamoter is filled with water ? if not how should i address the difference ?

    thanks in advance.

    If the change in pressure of the gas is much smaller than the absolute pressure of the gas, then the gas may be considered incompressible.
