Find reference air volume available while a receiver falls from start to minimum pressure with no compressor inflow.
Click the grid to add ordered vertices. Edit coordinates in mm; separate holes with a blank line. The last vertex closes to the first automatically.
Choose units and enter numbers. Full-width digits and fractions such as 1/8 or 1 3/8 are accepted. Changing a unit converts the entered value.
Reference calculation only. Results do not certify suitability for an actual design or its safety.
Inputs: select a blue symbol to edit Results: red-orange values and lines
3D shows an illustrative extrusion. Its display length does not enter the section calculations. Edit dimensions in 2D.
Vref=V(p1−p2)/pa · Tr/T; time=Vref/Qref.
Displayed values are rounded. Diagrams illustrate the calculation conditions. Initial material and fluid properties are examples; replace them with values for the actual material, temperature and conditions.
ReferenceEquations assume particular loads, supports and deformation ranges. Check inputs, units and the applicability of each equation. Diagrams explain conditions; they are not manufacturing drawings or proof of safety.
Material values are typical values or reference ranges, not certified product properties or ready-to-use design allowables. They vary with standards, product form, dimensions, temper and temperature. Check the specifications and inspection certificates for the actual product.
Displayed safety factors and checks apply only to the supplied inputs and calculation model. They do not automatically establish the safety of a complete design, including code compliance, service life, fatigue or joints. For actual design, manufacture and use, separately verify applicable regulations and standards, product specifications, and the necessary tests and engineering review.

停止した圧縮機のタンクが、開始圧から下限圧まで下がる間に使える基準空気量を求めます。
選択した形状・計算方法により、使う項目は変わります。実際の計算は上の図と入力欄で行えます。
Vref=V(p1−p2)/pa · Tr/T; time=Vref/Qref.
理想気体・等温のタンクで、供給停止、開始圧p1>下限圧p2の条件です。流量Qの基準温度・絶対圧は入力した基準に合わせます。断熱冷却、圧縮機の補給、漏れ、弁・配管の圧損、実際の機器の最低作動圧やタンク強度は別に確認します。
現在選択中の方法には、操作欄の「計算式・適用条件」を使ってください。参考計算であり、設計全体の安全性を保証するものではありません。
Find reference air volume available while a receiver falls from start to minimum pressure with no compressor inflow.
The selected model determines which of these inputs and outputs apply. Use the working diagram and input panel above to calculate.
Vref=V(p1−p2)/pa · Tr/T; time=Vref/Qref.
Ideal-gas isothermal receiver, no inflow, start p1 > minimum p2. Q must use the entered reference temperature and absolute pressure. Adiabatic cooling, compressor replenishment, leakage, valves/piping losses, actual equipment minimum pressure and tank strength are separate.
The displayed formula and conditions in the working panel apply to the currently selected model. Reference calculation only; it does not certify a complete design.
