PROFENG ENGINEERING

Engineering calculation hubs

Start from a discipline hub, then move between verified calculators, source-linked worked examples, glossary terms and a practical learning path.

Engineering Unit Conversion

Convert compatible engineering quantities with explicit unit definitions, fixed scale/offset relationships and dimensional checks.

300 current indexable toolsOpen hub →

Fluids, Pumps and Piping

Screen flow, pressure loss, pump power, NPSH, valve coefficients and related internal-flow relationships with explicit assumptions.

25 current indexable toolsOpen hub →

Heat Transfer

Work through conduction, convection, radiation and heat-exchanger screening calculations while keeping boundary conditions and property assumptions visible.

15 current indexable toolsOpen hub →

Mechanical Design

Screen stress, deformation, torsion, beam behavior, column stability, gears, springs and rotating-power relationships without presenting simplified results as final component designs.

25 current indexable toolsOpen hub →

HVAC and Refrigeration

Screen sensible loads, hydronic flow, air changes, duct velocity, fan power, envelope heat transfer and basic psychrometric relationships.
