Homework Help: Thermo Question

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

    The Variation of the density with depth h in a muddy lake is given by ρ=ρ0+kh, where ρ0= 1000kg/m^3 is the density at the surface and k=100kg/m^4

    Calculate the gauge pressure at a depth of 10m.

    Pressure is equal to Rho x g x h
    Where Rho is density of the substance, g is gravity and h is height.
    Because you've been asked to find gauge pressure, you can disregard the pressure exerted by the atmosphere.
