Quick Calc Hydraulics provides a snapshot of the hydraulic horsepower, jet velocity, and impact forces created at a jet nozzle orifice, which is installed in a drilling bit during earth-boring operations. The user provides numbers for fluid density, flow rates, TFA, and bit diameter, and Quick Calc Hydraulics then calculates the respective hydraulic parameters for conventional drilling fluids. Air, mist, and foam fluids are not supported at this time. The calculated results can be forwarded to anyone in the user’s contact list. ## Key features - Hydraulic horsepower calculation - Jet velocity calculation - Impact force calculation - Input fluid density, flow rates, TFA, and bit diameter - Share results with contacts ## Recent user reviews (9 of 9) All indexed reviews: https://appshunter.io/ios/app/quick-calc-hydraulics/id404002035/reviews.md ### 5/5 — Very useful Drill Bit App *2019-06-05, version 1.56* Very useful Drill Bit App ### 5/5 — Excellent NEW version! *2019-01-09* The NEW version is much easier to use and more functional than the OLD version. Great job development team!! ### 1/5 — Dir DD *2012-06-15* Absolutely no help, I am a SLB emp and this app is a joke, please people..... Get it together, we need info now, not waiting for an email reply for info about TFA, do not download this app ### 5/5 — Company men, don't go without! *2012-03-08* This app is one of my most used oil apps. I like to play with hydraulics, and this app is great for having more than one nozzle size on your bit. Gives pressure across the bit, hydraulic hp, TFA with diffusers, and more. A must have for any consultant. ### 5/5 — HSE SLB *2011-06-24, version 1.2* Sweet app. Would be great for bit hands in field. ### 5/5 — Reese *2011-06-24, version 1.2* It's a great app really wish I had a iphone. ### 4/5 — Good App *2011-04-13, version 1.1* Keep them coming. ### 5/5 — Great app written by a great guy!! *2011-04-10* Try it, you'll like it. ### 5/5 — Great tool for calculating bit hydraulics *2011-03-16* Great tool to use for calculating bit hydraulics. ## Frequently asked questions about Quick Calc Hydraulics ### What hydraulic parameters does Quick Calc Hydraulics calculate?
