Total Suction Head : The suction reservoir pressure head plus the static
suction head plus the velocity head at the pump suction flange minus the
friction head in the suction line.

Total Discharge Head : The discharge reservoir pressure head plus static
discharge head plus the velocity head at the pump discharge flange plus the
total friction head in the discharge line.

Total Differential Head : It is the total discharge head minus the total suction
head.
