Professional mechanical engineering on mobile — HVAC, fluids, machine design, vibration, IC engines. Multiple regional standards. Multiple languages. Offline. Pay once. VerMech is a professional offline-first mobile toolkit for mechanical engineers, students, and consultants — HVAC, thermo, fluids, heat transfer, machine design, refrigeration, vibration, IC engines, materials, and dynamics in one app. HVAC DESIGN - Cooling and heating load (CLTD, transmission, ventilation) - Outdoor-air requirement per occupant and per area - Duct sizing, fan power, psychrometrics (dewpoint, wet-bulb) THERMODYNAMICS - Ideal-gas state equation (PV = nRT) for the four unknowns - Rankine, Brayton, Otto, Diesel cycle efficiency - Vapor-compression refrigeration cycle COP and entropy change FLUID MECHANICS - Reynolds number, Moody-Colebrook friction factor - Darcy-Weisbach and Hazen-Williams pipe head loss - Open-channel flow — Manning's equation, Froude regime HEAT TRANSFER - Conduction — Fourier's law, multi-layer resistance - Convection — Dittus-Boelter, natural convection (Rayleigh) - Radiation — Stefan-Boltzmann, view factor - Heat-exchanger sizing — LMTD and effectiveness-NTU - Fin efficiency, insulation thickness sizing MACHINE DESIGN - Shaft — bending, torsion, DE-Goodman combined stress - Bolt — proof load, preload, torque-tension - Gear — module, pitch, bending stress capacity REFRIGERATION AND AC - Vapor-compression cycle — COP, refrigerant effect - Compressor power — isentropic, actual, shaft - Cooling tower — wet-bulb approach, range, makeup - Chiller efficiency — kW per ton, COP/EER/SEER conversion VIBRATION - Natural frequency, damping ratio, log decrement - Forced vibration — magnification, transmissibility - ISO 10816 severity bands for rotating machinery - Rotor balance grade selection (ISO 1940 G-grade) - Vibration isolation — spring selection IC ENGINES - Otto cycle efficiency (ideal + actual with combustion losses) - Displacement, BMEP and brake power - BSFC and brake thermal efficiency - Volumetric efficiency and mean piston speed - Air-fuel ratio — stoichiometric and excess-air analysis MATERIALS - Stress-strain — modulus, yield, ultimate strength - Fatigue — S-N (Basquin), endurance limit - Hardness — Brinell, Rockwell, Vickers conversion - Thermal expansion — linear coefficient, length change - Creep — Larson-Miller parameter; corrosion rate (mpy, mm/y) STATICS AND DYNAMICS - Truss — 2D analysis (Pratt, Howe, Warren) - Beam — shear and moment diagrams (simply-supported + cantilever) - Centroid and area moment of inertia (rectangle, circle, I-beam, T-beam) - Friction — block-on-incline, horizontal-pull (μ_s, μ_k) REGIONAL STANDARDS Switch design region in Settings — multiple regional code bases: United States, Europe / International, India, China, Japan and Thailand. Region-aware calculators update their limits and lookup tables to match the selected region's published engineering standards.
