About Engineering Toolkit Pro

Providing professional-grade, transparent, and interactive calculations for process, mechanical, and electrical engineers worldwide.

Professional Grade

Our formulas conform to standards set by the Hydraulic Institute (HI), ASME, and standard industrial engineering manuals.

Interactive Logic

Calculators update dynamically as you enter data, highlighting high velocity, cavitation hazards, and margin issues in real-time.

E-E-A-T Adherence

We believe in transparency. All fluid properties, calculation variables, and equations are explicitly fully visible.

Our Story & Goal

Founded by a team of mechanical and system design engineers, cheifsays.com (Engineering Toolkit Pro) was built to solve a simple problem: the reliance on outdated, closed-source Excel spreadsheets for core calculation workflows.

By offering modern, responsive calculations, high-fidelity PDF exports, and saving configurations to secure cloud spaces, we empower engineers to design piping layouts, size boiler feed pumps, and calculate motor capacities quickly and accurately.

Our Sizing Abstractions

Boiler Feed Pump Calculator

Calculates static pressure, friction losses, Total Dynamic Head (TDH), and NPSH margins.

Open

Friction Loss & Pipe Sizing

Uses Darcy-Weisbach and Colebrook-White to calculate velocity, friction factor, and pressure drops.

Open

Electric Motor Sizing

Sizes industrial electric motors based on load profiles, startup inertia, and service factors.
