Precision underground, progress above.

Inrock HDD Hydraulics Calculator is a designed specifically for professionals in the Horizontal Directional Drilling industry. The app enables users to perform calculations to use the available hydraulic energy efficiently to clear cuttings from the bottom of the hole. This improves tool-cleaning, reduces cuttings re-grind to increase the cutting action efficiency and reduces pack-off and balling-up risk. By minimizing mechanical wear on the shirttail and cutting structure, the tool can achieve its full bearing life potential (kRevs).

Key features:

• Comprehensive calculations. Instantly compute Delta P, Jet Velocity and material displacement by inputting pilot hole diameter, reaming diameter(s), mud weight, flow rate, and jet sizes (nominal size & count).
• Case comparison. Perform two simultaneous calculations using Case 1 and Case 2 to compare different scenarios side by side.
• Dynamic charting and summaries. Visualize results with interactive charts and view a summary of inputs and outputs for better analysis.
• Unit conversion flexibility. Switch between metric and US customary units effortlessly. All input and output values automatically convert when toggling between units.
• User-friendly interface. Navigate through three intuitive screens: Calculator, Chart, and Settings, designed for efficiency and accuracy.
