Head or rho*g*h is the driving force in fluid mechanics. Head loss can occur due to causes such as friction in pipelies, sudden bends, heat losses due to friction etc

Head Loss Fluid Mechanics

Head loss is just pressure lost. Feet of head is just a simple way to report the pressure loss, because most centrifugal pumps generate a given head pressure the pounds/inch^2 depends on the fluid density.
Also in the most fluid flow calculations the pressure drop is also calculated in feet of head and again the actual pounds/inch^2 or what ever pressure unit depends on the fluid density.

The head (in feet of liquid, any liquid) can be measured in a vertical clear plastic tube. If you connected clear plastic tubes (standpipes) at intervals along a pipe system you could measure the suction head at the inlet to a pump, the total head at the discharge of the pump and the head downstream of any valve, orifice or run of restricted piping. Comparing losses in fluid level would give you the head loss between any two chosen points. Of course you can use pressure gages instead of plastic tubing and convert the readings to feet of liquid knowing the specific gravity or density of the liquid.

In fluid dynamics, head is the difference in elevation between two points in a column of fluid, and the resulting pressure of the fluid at the lower point. It is possible to express head in either units of height (e.g. meters) or in units of pressure such as pascals (the SI unit). Head refers to the constant right hand side in the incompressible steady version of Bernoulli's equation

Head loss is an industry term for loss of fluid pressure due to height change, friction, shaft work, etc.

Simply put, Energy lost.
Head is a term for the potental energy that is stored in a system.
Head loss is the amout of differance form the potental to kenetic transfer.
