Pressure Drop vs Pipe Length
सूत्र
Darcy-Weisbach Pressure Drop
h_f = f x (L / D) x (V squared / 2g)
Where f is the Darcy friction factor, L is pipe length, D is diameter, V is velocity, and g is gravitational acceleration (32.174 ft/s squared). Multiply head loss in feet by 0.4333 to convert to psi.
हल किया गया उदाहरण
100 ft of 1-inch pipe carrying 10 GPM, friction factor 0.02.
- 01D = 1/12 = 0.0833 ft
- 02Area = pi x 0.04167 squared = 0.005454 sq ft
- 03V = (10/448.831) / 0.005454 = 4.09 ft/s
- 04h_f = 0.02 x (100/0.0833) x (4.09 squared / 64.348) = 6.24 ft
- 05Pressure drop = 6.24 x 0.4333 = 2.70 psi
अक्सर पूछे जाने वाले प्रश्न
How do I find the friction factor?
Use a Moody chart or the Colebrook equation. For clean copper pipe with turbulent flow the Darcy factor is typically around 0.018 to 0.025.
What pressure drop is acceptable?
A common design limit is 4 psi per 100 feet of pipe for residential supply lines.
