Using the data in Figure 5-19 and similar calculations as those given above, the
diesel fuel consumption rate as a function of drilling time (or drilling depth) can be
obtained. Figure 5-20 shows the diesel fuel consumption rate as a function of
drilling time (or drill depth) for this reciprocating piston compressor.

compressor of Illustrative Example 5.5c.
The approximate total diesel fuel needed to drill the borehole is given by the
integration of the area under the curve in Figure 5-20. This is approximately 360
