    1. The problem statement, all variables and given/known data

    A large water tank has an inlet pipe and an outlet pipe. The inlet pipe has a diameter of 1.89 cm and is 1.29 m above the bottom of the tank. The outlet pipe has a diameter of 5.47 cm and is 4.25 m above the bottom of the tank. A volume of 0.697 m3 of water enters the tank every minute at a gauge pressure of 1 atm.

    a) What is the velocity of the water in the outlet pipe?
    4.943 m/s

    b)What is the gauge pressure in the outlet pipe?

    2. Relevant equations



    3. The attempt at a solution

    a) What is the velocity of the water in the outlet pipe?
    4.943 m/s

    I found this part but i don't know how to do the second part.Please help me.
