smaller increments on the torque as the fricition applied to the torque are increased. Take the readings when the measured torque shows its maximum. Repeat this step until approximately 10 different settings are obtained with the last setting with the turbine stopped. 7. After the shaft is fully stopped, completely loosen the torque brake and zero the friction gage. 8. Increase discharge by opening the pipe inlet valve to a runaway speed of 2000 rpm and repeat steps 2 through 7. 9. Open drain valves and allow the basin to drain until only a trickle of water flows over the weir. Wait for weir flow to stop, then measure the water depth indicated by the point gage (H0in Figure 3).
