The performance of the rig was evaluated at various loads ranging from 0 to kg at a constant head of m 0 to kg at a constant head of Francis turbine test m and 0 to kg at a constant head of m of water respectively. Results showed that as rig energy unit the loads applied increases the water flow rate and input power to the rig increases reaches up to the discharge unit peak and then decreases at constant heads. Inverse relationship was observed between the torque speed unit power developed due to the loads applied and the speed of the runner of the turbine operating at a constant efficiency head. The excellent correlation between the torque generated and the speed were found to be at constant heads of m and m and at constant head of m of water. As the Article Info load applied increases the torque developed increases but at the same time speed of the runner of the Accepted turbine decreases. The output power developed by the rig increases with increase in load applied and 11 June 2020 reaches up to the peak values of HP at load of kg HP at load of kg and HP Available Online at load of kg at constant heads of m m and m of .
