Store description excerpt
EnergyVecta is an offline energy calculator that shows its work. FREE, forever: - Electricity bill from units and your tariff - Appliance running cost and standby (vampire) cost - AC / heater running cost, water-heater cost - EV charging cost and range per charge - Generator fuel estimate, UPS / inverter backup time - LED vs incandescent savings, motor consumption - Energy unit converters (kWh / MJ / BTU) - Solar quick-payback teaser CONSUMER PACKS (one-time, yours forever): - Solar PV, Ultimate (30 calculators): array & string sizing, inverter ratio, kWh/kWp yield with performance ratio, tilt & orientation factors, payback & LCOE-lite, solar-plus-storage sizing, and a guided Solar journey from sizing to payback - Battery & Storage, Ultimate (25 calculators): bank sizing from your load profile, usable capacity & depth of discharge, C-rate charge time, runtime under load, degradation estimate, cost per usable kWh, replacement horizon - Oil & Gas Field, Ultimate (32 calculators): Vogel IPR well-performance curves, volumetrics (OOIP/OGIP), pipeline & netback economics, and other field-reference calculators with textbook provenance - Home Energy Efficiency (25 calculators): heating-cost and degree-day calculators, insulation R-value and payback, heat-pump running cost, and other home-efficiency estimators PROFESSIONAL OIL & GAS PACKS (one-time, yours forever): - Gas Properties (28 calculators): z-factor by Brill & Beggs or Papay, Sutton/Wichert pseudo-criticals, density, viscosity, hydrates & inhibition, Wobbe index, ACFM/SCFM/MMSCFD conversions - Pipeline Hydraulics (30 calculators): Darcy & explicit friction (Swamee-Jain, Haaland), Weymouth & Panhandle A/B capacity, erosional velocity, line pack, hoop stress & %SMYS reference, surge screening by the Joukowsky relation, pig travel - Gas Compression (30 calculators): staging & ratios, adiabatic/polytropic head, power & discharge temperature, reciprocating displacement & capacity, surge margin, fan laws, fuel gas - Flare & Relief, Screening (22 calculators): KO drum settling & sizing, liquid seals, 40 CFR 63.670 NHV screens, API-520-form PSV reference, fire relief loads, blowdown, drum volumes - Gas Processing (30 calculators): separator sizing by Souders-Brown, binary flash, water content & TEG dehydration, amine sweetening, NGL content from composition, stabilization INTERACTIVE, NOT JUST A NUMBER - Scrub any input and watch every result update live. - Reverse-solve: pick the result you want and see what input gets you there. - Open any result to see the math behind it: the formula, the pack version, and how sensitive it is to each input. - Follow the Solar journey, size to yield to battery to payback, as one guided flow, or jump straight to a single calculator. WHY IT IS DIFFERENT - Runs entirely on your device. No account, no ads, no tracking, no network. - Every calculation comes from one of 10 cryptographically signed, verified calculation packs: 276 calcul
