Mini Hydro Power Plant. This is a self contained bench top unit for studying the power generation by a hydraulic turbine. The unit consist of a storage tank and a low head pump to simulate a dam reservoir, a cross flow hydraulic turbine, a generator which is connected to the turbine by a V-belt, a lamp load bank, a dynamometer, and measuring instrument.

TYPICAL EXPERIMENTS

Turbine torque vs speed at various heads and flow rates.
Mechanical power output vs speed for various heads and flow rates.
Mechanical efficiency vs speed for a given head and flow rate.
Electrical power output at various heads and flow rates.
Overall power plant efficiency at various electrical loads.
