The HydraulicsCalc provides you with important hole calculations for hydraulics, pressure loss and lag.
Hydraulics information includes nozzle velocity, impact force, HHP at bit, Pump HHP and equivalent circulating density.
Pressure loss calculations are provided for each segment of the drill string (internal and annular).
Lag is displayed in barrels, strokes, and minutes for kelly to bit and bit to surface.

Drill string information input ease of use is enhanced thru the the creation of customizable lists of casing, drill pipe, heavy weights, and drill collars. You don't have to scroll thru items you don't use and you enter information for string components only once.

Pump output is calculated by entering pump cylinder data and strokes per minute information. Inputs are provided for 1 to 9 jets of individual sizes for total flow area calculations.
