formula for 1" or smaller pvc volumes
(OP)
i need to figure out what the volume in GPM of a 1" pvc pipe 36" long at 3 ft/sec is. help please show math. also for a 3/4" pvc pipe same lenght and ft/sec.

RE: formula for 1" or smaller pvc volumes
Cap one end, stand upright on a scale to get the dry weight, then fill with water and re-weigh. Weight of water is 8.32487 pounds per gallon at 68 degrees F (measured in air at sea level). To double-check, empty the filled pipe into measuring buckets.
It's also theoretically possible to use the ID (inside diameter) of the pipe to calculate the volume. One US liquid gallon, by law = 231 cubic inches. If you know the pipe schedule (Schedule 40 is commonly used), search for pipe dimension tables.

A = Pi x R^2
D = 1 in = 0.083 ft
R = D/2
V = 3 ft/sec
1 cubic foot = 7.48 gallons (US ?)
1 minute = 60 seconds
flow = 7.3 GPM
The length of the pipe is not relevant
Do you really need to ask this ?

Best avoid advanced mathematics - simply empty the water from 180 feet of pipe into a large, graduated bucket.

This is a point that Canadian educators were never aware of with the result that generations of Canadian students were taught the wrong conversion from imperial gallons to US gallons.

Once we have the flow in imperial GPM, can we make it veddy veddy British and calculate the flow in furlongs per fortnight?
Please show the math.

I meant to suggest that we calculate the flow VELOCITY in furlongs per fortnight? However, mass flow calculated in cubic furlongs per fortnight has a certain veddy British charm. I like it.

My intensive research into determining the mathematical relationship between diameter and area of a pipe is wasted.
