Water Velocity Through Piping formula |
||
| \( v_w \;=\; \dfrac{ 4 \cdot Q_w }{ \pi \cdot d^2 } \) | ||
| Symbol | English | Metric |
| \( v_w \) = water velocity | \(ft\;/\;sec\) | \(m\;/\;s\) |
| \( Q_w \) = water flow rate | \(ft^3\;/\;sec\) | \(m^3\;/\;s\) |
| \( \pi \) = Pi | \(3.141 592 653 ...\) | \(3.141 592 653 ...\) |
| \( d \) = pipe inside diameter | \(in\) | \(mm\) |
Water velocity through piping is the speed at which water moves within a pipe.
Key Points about Water Velocity through Piping
Erosion - High velocities can lead to pipe erosion over time.
Noise - Faster water flow can increase noise levels.
Pressure Drop - Higher velocities result in greater friction losses, leading to increased pressure drop along the length of the pipe.
System Design - Proper velocity ensures efficient operation of plumbing systems, balancing between flow requirements and minimizing wear and energy costs.
