Use Pacesetter’s Quick Hydraulics Calculator to easily evaluate bit hydraulics. Enter the current bit size, flow rate, mud weight and nozzle sizes below to calculate hydraulic horsepower at the bit. Two copies of the calculator are provided to allow comparison between different scenarios. Values can be entered in any combination of metric and imperial units
