HOMER Logo

Type:	Input Variable
Units:	m
Symbol:	h

The total available vertical drop between the intake and the turbine. Friction losses in the pipeline between the intake and the turbine make the effective head somewhat less than the available head.

HOMER uses the available head to calculate the nominal hydro power and the effective head. It uses the effective head to calculate the power output of the hydro turbine.
