صيغ حجم الحوض
يحتوي هذا المرجع على صيغة الحجم لكل شكل من أشكال الأحواض المستخدمة في الواقع. نظرًا لأن أشكال الأحواض تتراوح من الصناديق البسيطة إلى الأسطوانات والمضلعات والمنحنيات المركبة، فلا توجد صيغة واحدة تنطبق على جميع الأحواض. استخدام الصيغة الخاطئة قد يؤدي إلى أخطاء بنسبة 10–30 ٪. قياس حجم الحوض.
صيغة الحجم الأساسية
تبدأ جميع حسابات الحجم بنفس المفهوم: اضرب مساحة المقطع العرضي للحوض في ارتفاعه.
V = L × W × H
- L — الطول الداخلي (أطول بُعد أفقي)
- B — العرض الداخلي (من الأمام إلى الخلف)
- H — ارتفاع التعبئة (من القاع إلى خط الماء)
إذا تم القياس بالبوصة: اقسم الناتج على 231 للحصول على جالونات أمريكية. إذا تم القياس بالسنتيمتر: اقسم على 1000 للحصول على لترات.
صيغ الأحواض القياسية
تشترك الأحواض القياسية في شكل المنشور المستطيل. الصيغ متطابقة؛ تختلف النسب فقط.
Rectangular Aquarium
V = L × W × H
Measure the inside dimensions of your rectangular tank from glass to glass, not including the frame or trim. For length, measure the longest horizontal edge; for width, measure front to back; for height, measure from the inner bottom to the desired water line.
Cube Aquarium
V = S³
Measure any one inside edge of the cube from glass panel to glass panel. All three dimensions should be identical; if they differ slightly, use the rectangular calculator instead for a more accurate result.
Breeder Aquarium
V = L × W × H
Measure inside dimensions just like a standard rectangular tank. Breeder tanks are distinguished by a width-to-height ratio greater than 1:1. If your tank is taller than it is wide, it is likely a standard rather than a breeder.
Shallow Aquarium
V = L × W × H
Measure the interior length, width, and height from the inside glass surfaces. Shallow tanks typically have a height under 12 inches. Include only the water-filled portion when calculating volume; do not include any exposed land area in a paludarium.
صيغ الأحواض المنحنية
تتطلب الأحواض المنحنية صيغًا من الهندسة الدائرية. المتغير الرئيسي لجميع الأشكال الدائرية هو نصف القطر (نصف القطر الداخلي).
Bow Front Aquarium
V = (L × D × H) + (π × (L÷2) × B × H) ÷ 2
Measure the straight back panel for the flat depth. For the bow depth, measure from the plane of the back glass to the furthest point of the curved front panel, then subtract the flat depth. The length is measured along the back panel from side to side.
Cylindrical Aquarium
V = π × r² × H
Measure the inside diameter of the cylinder at the widest point and divide by two to get the radius. For acrylic cylinders, be sure to measure inside the wall, not outside. Height is measured from the interior bottom to the water line.
Half Cylinder Aquarium
V = (π × r² × H) ÷ 2
Measure from the flat back wall of the tank to the outermost point of the curved front to get the radius. Alternatively, measure the full width of the flat back panel and divide by two. Height is measured inside from bottom to water line.
Elliptical Aquarium
V = π × a × b × H
Measure the longest inside diameter and divide by two for the semi-major axis. Then measure the shortest inside diameter (perpendicular to the first) and divide by two for the semi-minor axis. Height is inside bottom to water line.
Bullnose Aquarium
V = ((L - r) × W × H) + (π × r² × H) ÷ 2
Measure overall length from the flat end to the farthest point of the curved end. The bullnose radius is the distance from the center of the curve to the curved glass surface. Width is measured across the flat sides. Height is inside from bottom to water line.
Round End Aquarium
V = ((L - W) × W × H) + (π × (W÷2)² × H)
Measure the total inside length from the outermost curve on one end to the other. Width is the inside distance between the two long flat sides, which also equals the diameter of each semicircular end cap. Height is inside bottom to water line.
Fish Bowl
V = (π × d³) ÷ 6
Measure the widest inside diameter of the bowl from one inner wall to the opposite inner wall. For bowls with a flat bottom, measure at the widest horizontal cross-section, not at the base. Note that actual water volume will be less than the full sphere because bowls have an open top.
صيغ أحواض الزاوية
صُمّمت أحواض الزاوية لزوايا الغرف بزاوية 90 درجة. منشور الزاوية له بالضبط نصف حجم المستطيل بنفس أبعاد الجدار.
Corner Bow Front Aquarium
V = (L × D × H) + (π × (L÷2) × B × H) ÷ 2
Place a straight edge across the back corner to define the flat depth plane. Measure the bow depth from that plane to the outermost point of the curve. Length is measured along the straight back edge where the two wall-facing panels meet.
Corner Cylinder Aquarium
V = (π × r² × H) ÷ 4
Measure along either flat back panel from the corner to the edge where the curve begins; this distance is the radius. Both flat panels should be equal in length. Height is measured inside from the bottom to the water surface.
Corner Aquarium
V = ½ × a × b × H
Measure the inside length of each back panel that rests against the wall. These are the two legs of the right triangle. They do not need to be equal. Height is measured inside from the bottom to the waterline. The diagonal front panel length is not needed for the volume calculation.
صيغ الأحواض المضلعة
تستخدم الأحواض المضلعة — السداسية والثمانية والخماسية — صيغ مساحة المضلع المنتظم. نظرًا لأن جميع الأضلاع متساوية، يكفي قياس طول ضلع واحد.
Hexagonal Aquarium
V = (3√3 ÷ 2) × s² × H
Measure the inside length of any one of the six identical flat panels. All sides of a regular hexagon are equal, so a single measurement is sufficient. If the sides are unequal, the tank is not a true hexagon and this formula will be approximate.
Octagon Aquarium
V = 2(1 + √2) × s² × H
Measure the inside length of any one of the eight identical panels. For accuracy, confirm that all eight sides are equal. If your tank has alternating long and short sides, it is not a regular octagon and this formula will not apply exactly.
Pentagon Aquarium
V = (√(25 + 10√5) ÷ 4) × s² × H
Measure the inside length of one of the five equal panels. Verify that all five sides are the same length. The pentagon formula assumes a regular pentagon; irregular five-sided tanks would need to be decomposed into simpler shapes for calculation.
صيغ الأحواض الخاصة
تتطلب الأشكال الخاصة مثل الأحواض على شكل L وشبه المنحرف تقسيم القاعدة إلى أقسام هندسية أبسط.
L-Shaped Aquarium
V = (L1 × W1 × H) + (L2 × W2 × H)
Divide the L-shape into two non-overlapping rectangles. Measure the inside length and width of each rectangle separately. Both sections must share the same height. Be careful not to double-count the overlapping corner area where the two sections meet.
Trapezoid Aquarium
V = ½(b1 + b2) × D × H
Measure the inside length of the front panel (base 1) and the inside length of the back panel (base 2). Depth is the perpendicular distance between these two parallel panels measured inside. Height is inside from the bottom to the water line.
