Bernoulli's equation is an expression of:

the conservation of mass
the conservation of total energy
the conservation of kinetic energy
the conservation of momentum
the conservation of velocity

My ans:
the equation states that it should be a constant when there is a streamline flow so I am guessing that it describes the conservation of total energy, in fluids?

  1. Yes, the units of the Bernoulli equation is energy density (Joules/m^3)

    You might work them out to prove that.

  2. Using conservation of energy, find the speed vb of the block at the bottom of the ramp
