Ҳисобкунаки ҳаҷми тана ва бор

Ҳисоб кунед тана Ҳаҷм from small-end diameter, butt-end diameter, and дарозӣ, then тахмин бор кардан Вазн from Зичӣ.

Editable Ҳаҷм rules and Зичӣ tables make it easier to adapt the page to regional тана grading and мошини боркаш loading workflows.

Дастгирӣs Smalian, Frustum, Mean diameter, and custom multiplier rules Ҳисоб кунедs партия rows for multiple тана lots in one screen Неrmalizes Зичӣ to kg/m3 and Ҳаҷм to m3 internally Тахмин кунедs мошини боркаш бор кардан Нисбат and тахминӣ мошини боркаш Шумора from payload

Ин абзор чӣ кор карда метавонад

  • Тахмин кунед тана Ҳаҷм from small-end diameter, butt-end diameter, and дарозӣ with a choice of Ҳаҷм rule.
  • Табдил диҳед Зичӣ tables to kg/m3 internally so that local units and истинод values stay comparable.
  • Track many тана lots at once and нигоҳ a rough inventory record for the yard or landing.
  • Тахмин кунед мошини боркаш бор кардан Нисбат, remaining payload, and тахминӣ мошини боркаш Шумора when capacity is entered.
  • Сабт the current conditions in the браузер, a мубодила URL, JSON, or CSV depending on how much маълумот you want to carry.

Чӣ тавр истифода бурдан

  1. Интихоб кунед the measurement system and the default diameter, дарозӣ, and Вазн units.
  2. Ворид кунед small-end diameter, butt-end diameter, дарозӣ, and Шумора for each тана lot.
  3. Pick a Ҳаҷм rule and a Зичӣ profile, then санҷ the resulting Ҳаҷм and Вазн.
  4. Add мошини боркаш capacity if you want a payload Нисбат and an тахминӣ мошини боркаш Шумора.
  5. Истифода баред JSON or CSV export to мубодила the current state, or сабт the page locally for later истифода.

Examples

Metric log lot

Input

Small-end 18 cm, butt-end 28 cm, length 4 m, count 20, density 860 kg/m3, rule Smalian

Output

About 0.174 m3 per log, 3.48 m3 per lot, and about 2.99 t total weight

Imperial log lot

Input

Small-end 7 in, butt-end 11 in, length 16 ft, count 10, density 54 lb/ft3, rule Smalian

Output

About 7.42 ft3 per log, about 399 lb per log, and about 3,990 lb total weight

Regional override

Input

Apply a Smalian × 0.92 regional factor and replace the density table with a local reference set

Output

The difference from the default values becomes visible so that teams can align on one shared assumption

Луғат

Диаметри нӯги борик

The diameter at the thinner end of the тана. Local rules may treat bark inclusion differently.

Диаметри қисми ғафс

The diameter at the thicker end of the тана. Some regional rules call it the butt-end diameter.

Smalian

A Ҳаҷм формула that multiplies the average of the two end areas by the тана дарозӣ.

Frustum

A frustum approximation that uses both end diameters and the тана дарозӣ.

Density

масса per Воҳид Ҳаҷм. It changes a lot with species, намӣ content, and bark assumptions.

Нисбати бор

The мубодила of мошини боркаш payload used by the current бор кардан, shown as a percentage of the maximum payload.

Formulas

  • A(d) = π × d2 / 4
  • Smalian: V = L × (As + Ab) / 2
  • Frustum: V = π × L × (ds2 + ds × db + db2) / 12
  • Mean diameter: V = π × L × ((ds + db) / 4)2
  • Weight = Volume × Density
  • Load ratio = Total weight / Truck max payload
  • Approximate truck count = ceil(Load ratio)

Саволҳои маъмул

Which Ҳаҷм rule should I истифода?

Истифода баред the regional rule that your yard, mill, or buyer expects. When не local rule is defined, start with Smalian.

Can I ворид mixed units?

Ҳа. The page accepts Воҳид-tagged values such as 18 cm, 7 in, 16 ft, 54 lb/ft3, and 0.86 g/cm3.

Can I мубодила custom rules or Зичӣ tables?

Ҳа. Истифода баред JSON export and import for the full libraries. The мубодила URL is for the current operating state only.

Does the мошини боркаш payload санҷ enforce legal limits?

Не. It only shows an тахминӣ Нисбат and мошини боркаш Шумора. Always confirm legal and company limits separately.

Can I истифода this on mobile?

Ҳа. The page switches to input and output tabs on small screens, and the main calculation stays in the браузер.

Эзоҳҳои муҳим

  • Зичӣ changes with species, намӣ content, bark, and local measuring practice.
  • Ҳаҷм rules also vary by region. Always нигоҳ the rule name and basis visible when you мубодила the натиҷа.
  • мошини боркаш payload натиҷаҳо are тахминӣ only. Confirm the actual vehicle spec, road rules, and company policy before dispatch.
  • Ин саҳифа барои арзёбӣ ва идоракунии саҳн аст, на барои санҷиши аз ҳад зиёди қонунӣ ё тарҳрезии конструктивӣ.
