Hydra - Hydraulic Pipeline Calculator

Overview

Hydra is a browser-based hydraulic calculator for pressure drop, flow rate, diameter, and length calculations in gas and liquid pipelines. It uses a shared hydraulic solver service, structured pipe and fluid data, unit handling, and PDF output for engineering documentation.

Key Features

• Gas & Liquid Solver Modes
• Pipe & Fluid Data
• Multiple Calculation Modes
• Pressure Unit Handling
• PDF Engineering Reports

Challenge

Pipeline engineers needed quick, repeatable calculations without desktop installation, manual lookup tables, or spreadsheet-based unit conversions. Existing workflows made it difficult to keep calculation methods, pipe data, and fluid properties consistent across teams.

Solution

MetaEnergy built Hydra as a React/TypeScript frontend connected to a C++ gRPC solver through API services. The app retrieves fluid properties, fitting coefficients, and pipe specifications from database tables, supports gas/liquid mode selection, and handles gauge/absolute pressure conversion.

Impact & Results

• Faster browser-based calculations, fewer manual input errors, consistent methods across standalone and platform workflows, and clean PDF reports for engineering review and handover.

Simulation & Infrastructure Intelligence

Engineering models that let operators test scenarios before decisions reach the field

MetaEnergy builds simulation and infrastructure-intelligence tools for teams that need to understand how gas, liquid, or utility networks behave under changing conditions. The goal is not only calculation, but repeatable engineering decision support.

What we deliver

• Hydraulic simulation models
• Steady-state and transient analysis
• Pressure and flow studies
• Scenario comparison
• Constraint and bottleneck analysis
• Investment-planning support

Use this service when

• You need to validate a hydraulic scenario before field action
• You need to evaluate pressure, flow, capacity, or network constraints
• You need repeatable engineering reports instead of one-off spreadsheet calculations
• You are planning reinforcement, looping, or capacity upgrades
