Eight topics covering the full undergraduate fluid mechanics curriculum.
Hydrostatics, buoyancy, pressure measurement, and surface effects
Conservation laws, flow measurement, internal and external flow, and fluid forces
Convective heat and mass transfer, heat exchangers, and thermal analysis
Free surface flows, channels, hydraulic structures, and coastal hydraulics
High-speed gas dynamics, shocks, isentropic relations, and nozzle flow
Pumps, fans, turbines, and rotating machinery performance
Pipe sizing, friction factors, series/parallel networks, and water hammer
Every calculator shows the complete working — formula, substitution, intermediate values, and final result. Not just the number.
All 100 equations and step-by-step calculations are typeset with KaTeX for proper mathematical notation — subscripts, superscripts, Greek letters.
Select any combination of equations, add your course code and exam name, and print a clean single-page reference sheet.
Adaptive practice problems at your chosen difficulty — with progressive hints, full worked solutions, and a contextual tutor you can ask questions at any step.
24 categories and 185 units covering all common engineering quantities — pressure, viscosity, thermal conductivity, rotational speed, and more.
Fluid properties for water and air across temperature ranges, pipe roughness values, minor loss coefficients, and dimensionless number summaries.
