How do you find the diameter of a pipe with velocity?
How do you find the diameter of a pipe with velocity?
The equation for pipe diameter is the square root of 4 times the flow rate divided by pi times velocity. For example, given a flow rate of 1,000 inches per second and a velocity of 40 cubic inches per second, the diameter would be the square root of 1000 times 4 divided by 3.14 times 40 or 5.64 inches.
How do you calculate pipe diameter by velocity and flow?
With pipe diameter calculator pipe internal diameter is calculated using the simple relation between flow rate, velocity and cross-section area (Q=v·A).
What is pipe diameter?
When it comes to measurement of pipe, it is measure by the inside diameter, often called the nominal diameter. Nominal Pipe Size (NPS) is a North American set of standard sizes for pipe. The term nominal refers to pipe in non-specific terms and identifies the inside diameter with a non-dimensional number.
How do I calculate water pipe size?
1 inch= 25.4mm, 1 ft. = 304.8mm, 1 gallon/m=3.785L/m. Water velocity should not be greater than 2.438m/s at valve seat to prevent noise and erosion. So, Pipe area should be at least equal to water flow rate divided by eight.
What is fluid velocity in pipe?
Pipe velocity is an area averaged property which is independent of the pipe’s cross-sectional flow distribution and whether the flow is laminar or turbulent. For example, along the central axis, fluid may be travelling at twice the calculated pipe velocity.
What is the diameter of a pipe?
The outside diameter is from outside edge to outside edge across the pipe. To find it, measure around the circumference of the pipe with flexible measuring tape. Divide the circumference by pi, or about 3.14159.
What is the diameter of 3/4 pipe?
1.050″
Steel Pipe Sizes – Schedule 40
| NPS | Outside Diameter (in) | Weight (lb/ft) |
|---|---|---|
| 3/4 | 1.050″ | 1.13 lb/ft |
| 1 | 1.315″ | 1.68 lb/ft |
| 1-1/4 | 1.660″ | 2.27 lb/ft |

What size is 3/4 pipe?
Tubing is measured by the OUTSIDE DIAMETER (O.D.), specified in inches (e.g., 1.250) or fraction of an inch (eg. 1-1/4″). Pipe is usually measured by NOMINAL PIPE SIZE (NPS)….OD and Nominal Pipe Size.
| Nominal Pipe Size | Outside Diameter (inches) |
|---|---|
| 3/4″ | 1.05 |
| 1″ | 1.315 |
| 1-1/4″ | 1.66 |
| 1-1/2″ | 1.9 |
