Homework Help: Water Pressure Velocity Acceleration (dv/dt)

  1. Mar 30, 2012 #1
    I am having trouble solving this problem. Any assistance is greatly appreciated.

    Water is discharged from a pipeline at a velocity of v given by v=1192p^(1/2), where p is the pressure (in psi). If the water pressure is changing at a rate of 404 psi/second, find the acceleration (dv/dt) of the water when p = 34 psi.

    I have soved the v' to equal: 596p^(-.5).
    Does dv/dt = 596^(-.5)/t for (dv/dt)?
    What's the next step?
