Some Fluids questions

  1. Sep 8, 2009 #1
    I stucked with my hard fluid questions. I don't know what should I do first.
    So, Please describe detail as much as possible.
    Thanks for Physics Genious guys.


    2. A house at the bottom of a hill is fed by a full tank of water 5.0m deep and connected to the house by a pipe that is 110m long at an angle of 58 degree from the horizontal. (a) Determine the water gauge pressure at the house. (b) How high could the water shoot if it came vertically out of a broken pipe in front of the house?

    what should I use equation for (a) and how it works for (b)


    3. A spherical balloon has a radius of 7.35m and is flled with helium. How large a cargo can it lift, assuming that the skin and structure of the balloon have a mass of 930kg? Neglect the buoyant force on the cargo volume itself.

    So F(b) = (mass of helium + mass of cargo) X 9.8

    F(b) = Density of air X volume X 9.8

    9.8 cancels out on both sides.

    Density of air is 1.29 kg/m^3 so
    1.29V = (mass of helium + mass of cargo)

    I cannot go further after this step. Please answer what should I do for next, and please let me know that if I am wrong for some equation during the process.
