Dear All,
What exactly is head and what is it's significance in pressure measurement?
According to wiki, head is a concept that relates the energy in an in compressible fluid to the height of an equivalent static column of that fluid.Does that mean we are relating the total energy of a moving fluid to the energy(potential)of a fluid at rest?The moving fluid possess potential energy as well so why are we relating it to energy of a fluid at rest.I suppose potential energy is the only type of energy possessed by a fluid at rest.Sorry If the question sounds nebulous.I just don't get the intuition behind it
