2.6 Flow Requirements
Figure 2-4, Pressure Drop Values, illustrates the pressure drop for four different pipe sizes. The
graph can be used to calculate the minimum source water pressure.
1. Enter the graph at the required GPM and note the pressure drop figures for the different
pipe sizes.
2. Multiply the pressure drop (PSI/FT) by the length in feet of each pipe size used from the
water source to the intensifier. Add the values together for a total pressure drop value.
3. Add 30 to the total pressure drop to determine the minimum flowing, source water
pressure required to provide adequate supply to the intensifier.
Cutting water and cooling water capacity should be calculated separately. Note that the cutting
water requirements represent instantaneous, not average, demand.
The machine will not start if
the inlet cutting water pressure drops below 30 psi (2 bar).
