Estimate force from a free jet striking a stationary flat plate normally.
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.
A=πD²/4; v=Q/A; F=ρQv.
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.

静止した平板へ直角に当たる噴流の流量・径から、理想的な押す力を求めます。
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。
A=πD²/4; v=Q/A; F=ρQv.
大気中の非圧縮噴流が全量、十分大きい静止平板へ直角に衝突し、板に沿って流れ出る理想運動量モデルです。飛散・損失・非一様速度、圧力を持つ配管エルボ、ウォーターハンマー、板の強度・変形は含みません。
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。
Estimate force from a free jet striking a stationary flat plate normally.
The selected model determines which of these inputs and outputs apply. Use the working diagram and input panel above to calculate.
A=πD²/4; v=Q/A; F=ρQv.
Ideal incompressible free jet in air, fully intercepted normally by a large stationary plate and discharged along it. Splash losses, nonuniform velocity, pressurized pipe elbows, water hammer and plate strength/deformation are excluded.
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.
