Fluid Machines see prob 5 on prob sheet:

Fluid machines can be analyzed using conservation of energy which in this case can be taken as work on the machine equals work done by the machine since the energy of the machine itself doesn't change. Fluids do work by exerting a pressure times an area over a distance i.e.

W= P x A xd

so if work is done on (energy put into) the machine at point 1 and the machine does work at point 2, we have:

P1 x A1 x d1 = P2 x A2 x d2
