Water Hammer Pressure Calculator helps contractors and tradespeople accurately size, spec, and estimate materials and systems.
公式
Surge Pressure = ρ × a × V / g where a=wave speed, V=velocity change
分步指南
- 1Calculate wave speed, multiply by velocity change and density
- 2Apply the formula using your project measurements
- 3Add required safety factors or waste allowances per code
例题解析
输入
V=5 fps change, a=4000 fps wave speed
结果
Surge = (62.4 × 4000 × 5) / (32.2 × 144) = 269 PSI
常见错误注意事项
- ✕Not applying code-required safety factors or derating
- ✕Forgetting to account for waste and cut losses in material estimates
