Figure 8.8c . Torque in mud test. Figure 8.8d . Power in mud test.
The above results assume that density alone changes. Now, we keep the
mud used, but double the mud flow rate from 200 gpm to 400 gpm. This affects
the results in Figures 8.8c and 8.8d as follows. The torque will increase by 2 2 or
4 times, while the power will increase by 2 3 or 8 times. Thus, the torque number
becomes 166.7 u 4 or 667 while the power number becomes 4,200 u 8 or
33,600. Because the flow rate has doubled, the turbine no load speed will also
double; the 104.7 now becomes 209.4. The screen in Figure 8.7 becomes
