Tank Volume API

salutare 3,924 Abbonati

Tank-gauging geometry as an API, computed locally and deterministically. The horizontal-cylinder endpoint computes the liquid volume in a partially-filled horizontal cylindrical tank from the fill height, the radius (or diameter) and the length, V = L·[r²·acos((r−h)/r) − (r−h)·√(2rh−h²)] — the non-linear relationship that makes a horizontal tank read so unintuitively, e.g. a tank filled to a quarter of its diameter holds only about 20 % of its capacity, while half height is exactly half full. The vertical-cylinder endpoint gives the straightforward V = π·r²·h for an upright tank. The sphere endpoint computes the volume in a spherical tank filled to a height h as the spherical cap V = π·h²·(3r−h)/3, exactly half the sphere at h = r. Every response returns the liquid volume in cubic metres and litres, the full capacity, and the fill percentage. All lengths are in metres. Everything is computed locally and deterministically, so it is instant and private. Ideal for industrial, fuel-station, agriculture, water-utility, chemical-storage and process app developers, tank-gauging, dipstick-to-volume and inventory tools, and IoT level sensors. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is tank volume by geometry; for flow rate through a pipe use a flow-rate API.

Tank Volume API

Tank volume and fill-level maths as an API, computed locally and deterministically. The volume endpoint gives the total capacity — in litres, US gallons and cubic metres — of a vertical cylinder, horizontal cylinder, rectangular tank, sphere or capsule, from its dimensions in metres, centimetres, millimetres, feet or inches. The fill endpoint computes the volume of liquid and the percent full at a given fill depth, using the exact geometry for each shape — including the circular-segment formula for a horizontal cylinder (where the level is famously non-linear) and the spherical-cap formula for a sphere. The level endpoint is the inverse "dipstick" calculation: it finds the depth that corresponds to a target volume or a target percentage, solving the segment geometry by bisection. Everything is computed locally and deterministically, so it is instant and private. Ideal for fuel, water, oil and chemical tank monitoring, agriculture and irrigation, process and industrial tooling, and tank-gauging and dipstick apps. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is tank-gauging geometry; for swimming-pool volume and chemical dosing use a pool API, and for plain unit conversion use a unit-conversion API.

API de Gestión de Inventarios

Matemáticas de gestión de inventarios como API, calculadas local y determinísticamente. El endpoint eoq calcula la cantidad económica de pedido, EOQ = √(2·D·S/H) a partir de la demanda anual, el costo por pedido y el costo de mantenimiento por unidad por año — el tamaño de pedido que minimiza el costo total — y devuelve el número de pedidos por año, los días entre pedidos y los costos anuales de pedido, mantenimiento y totales (que son iguales en el EOQ). El endpoint reorder calcula el punto de reorden, demanda diaria × tiempo de entrega + stock de seguridad, el nivel de stock en el que se debe realizar el próximo pedido. El endpoint safety calcula el stock de seguridad para un nivel de servicio objetivo, Z × σ × √tiempo_de_entrega, donde Z es el valor de la distribución normal para el nivel de servicio (95 % da 1.645) encontrado mediante un cálculo exacto de la inversa de la normal, por lo que cualquier nivel de servicio funciona. Todo se calcula local y determinísticamente, por lo que es instantáneo y privado. Ideal para desarrolladores de aplicaciones de comercio electrónico, venta minorista, almacenes y cadena de suministro, herramientas de planificación de existencias y adquisiciones, y paneles de operaciones. Cálculo local puro — sin clave, sin servicio de terceros, instantáneo. En vivo, nada almacenado. 3 endpoints. Esto es optimización de inventarios; para punto de equilibrio y costo-volumen-beneficio, use una API de punto de equilibrio.

Craps Odds API

Craps odds maths as an API, computed locally and deterministically and exactly — the dice probabilities behind the table, derived from the 36 ways two dice fall, not pulled from a chart. The come-out endpoint gives the come-out roll: the pass line wins on a 7 or 11 (8 of 36, 22.2 %), loses on craps 2, 3 or 12 (4 of 36, 11.1 %), and otherwise sets a point (24 of 36, 66.7 %). The point endpoint gives the odds of making a point before a seven — probability = ways(point) ÷ (ways(point) + 6) — so a 6 or 8 makes 45.5 % of the time and a 4 or 10 only 33.3 %, with the TRUE odds (2:1, 3:2, 6:5) the free odds bet behind the line pays at zero house edge. The bet endpoint gives the house edge of the main bets: the line bets at 1.41 % (pass) and 1.36 % (don't) and place 6/8 at 1.52 % are the table's best, while place 4/10 (6.67 %), the field and proposition bets like any seven (16.67 %) bleed you. Everything is computed locally and deterministically, so it is instant and exact. Ideal for craps and casino-game apps, gambling-education and odds tools, game-design back-ends, and probability teaching. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 compute endpoints. Educational — not betting advice; back the line with free odds.

Lottery Odds API

Lottery combinatorics as an API, computed locally and deterministically and exactly — the real odds behind a ticket, the maths the jackpot poster never shows. The odds endpoint gives the jackpot odds of a pick-N game as the number of possible tickets, C(pool, picks), times the bonus-ball pool if there is one: a 6/49 game is 1 in 13,983,816, a 5/69-plus-1/26 Powerball-style game is 1 in 292,201,338, and every single line is equally unlikely. The match-odds endpoint gives the chance of matching exactly k of the main numbers — a prize tier — from the hypergeometric formula C(picks, k)·C(pool−picks, picks−k) ÷ C(pool, picks), so matching 3 of 6 in a 6/49 game is about 1 in 57. The expected-value endpoint turns a jackpot and ticket price into the expected value and the break-even jackpot (price × the odds), the threshold a jackpot must clear before a ticket is even theoretically worth it — before a shared jackpot, lump-sum and tax pull it back under. Everything is computed locally and deterministically, so it is instant and exact. Ideal for lottery and odds apps, gambling-education and responsible-play tools, probability teaching, and game back-ends. Pure local computation — no key, no third-party service, instant. Exact combinatorics. Live, nothing stored. 3 compute endpoints. Educational — not gambling advice; the odds are always against you.
