Table 4-1 10 gives the performance characteristics for various circulation
flowrates for the 212-stage, 6 $in. outside diameter turbine motor described
briefly in Table 4-109 and shown graphically in Figure 4-192.
Table 41 11 gives the performance characteristics for various circulation flowrates
for the 318-stage, 6 $-in. outside diameter turbine motor described briefly in
Table 4-109. Figure 4-194 shows the performance of the 318-stage turbine motor
at a circulation flowrate of 400 gal/min and mud weight of 10 lb/gal.
The turbine motor whose performance characteristics are given in Table 41 10
is made up of two motor sections with 106 stages in each section. The turbine
motor whose performance characteristics are given in Table 4-111 is made up
of three motor sections.
