Homework Help: Fluid Mechanics - statics/control volume

  1. Apr 6, 2010 #1
    Hi guys! here comes the question:


    I need some tips and guideness to make an attempt at it. I'm kind of confused if im supose to use basic equations in integral form for control volume here and if so then how?

    If the reference material is water then a substance with a relative density less than one will float in water, but i guess its not that simple because of the tube hole under the sphere..

    help? :~)
