# EnergyMindAI Bit Hydraulics Studio v2.1.0

Portable native Windows engineering application paired with the EnergyMindAI tutorial [Bit Nozzle TFA Calculator in Python](https://energymindai.com/2026/08/29/bit-nozzle-tfa-calculator/).

## What the application does

- Equal or mixed bit-nozzle configurations entered in 32nds of an inch
- Total flow area (TFA), average jet velocity and nozzle pressure loss
- Bit hydraulic horsepower (HHP) and hydraulic horsepower per square inch (HSI)
- Surface, drillstring/BHA, motor and annular pressure-budget breakdown
- Estimated standpipe pressure, pressure margin and SPP utilization
- Bit pressure-loss share and maximum-flow screening at the entered SPP limit
- Equal-nozzle sensitivity from a user-defined minimum to maximum size
- Multi-parameter sensitivity studies with up to 500 combinations across nozzle size, flow, mud weight, discharge coefficient, bit diameter, individual pressure losses and maximum SPP
- Four-panel graph dashboard covering pressure response, HSI, jet velocity, margin heatmaps and ranked feasible cases
- Automated engineering review flags and field-use cautions
- Saved JSON project files
- Export package containing CSV sensitivity, project data and a text engineering report
- Comprehensive branded Microsoft Word (`.docx`) and PDF reports with assumptions, inputs, executive summary, embedded graphs, ranked cases and the complete sensitivity table

The default tutorial case reproduces approximately 0.33134 in² TFA, 484.2 ft/s jet velocity, 2,099 psi nozzle loss, 612.4 bit HHP and 10.79 HSI.

## Installation and trial

1. Extract the downloaded ZIP.
2. Run `EnergyMindAI-Bit-Hydraulics-Studio.exe`.
3. No Python, browser runtime, .NET installation or other engineering software is required.

The application includes a 30-day free trial starting on first use. After the trial, copy the machine code shown in the application and request a signed monthly authorization code from EnergyMindAI. Authorization codes are tied to one computer and include an expiry date.

Windows may show a SmartScreen notice because the executable is not code-signed. Download only from the official EnergyMindAI article.

## Engineering notice

This application is an engineering screening and training aid, not an approved drilling program. Confirm the complete hydraulics model, current pump curves, motor limits, bit supplier nozzle limits, ECD, hole cleaning and the approved operating envelope before field use.
