You can run it 10 feet with NO fittings.
Nil. You need a pressure differential for flow to take place.
what amount of pressure you need to hidrotest 8 inch pipe
The recommended pressure rating for 1.5 inch schedule 40 pipe is 130 psi.
The maximum pressure rating for a 2 inch schedule 80 PVC pipe is typically around 400 psi.
The maximum pressure rating for a 2 inch schedule 80 PVC pipe is typically around 400 psi.
you have a severe pressure drop and a loss of velocity
To calculate pressure in pounds per square inch (psi) for a fluid flowing through a pipe, you need the fluid's density. Without knowing the density, we cannot directly determine the pressure using just the pipe size and velocity. The pressure would depend on the specific fluid being transported in the pipe.
The pressure rating for schedule 80 pipe is typically around 200 psi (pounds per square inch).
i believe the pressure does not change but the volume of water you will be able to use will be less
That's 3/4" pipe, not 3.4" prehaps it would deliver more pressure through the 1/2 inch pipe than 3/4 inch. 3/4" pipe will be less restrictive over the course of the run. Otherwise, no. 1/2" Copper Pipe will do fine, since it has a smoother bore, less restrictive, no lime and rust build-up. The only reason for you to use 3/4" pipe is if you want more volume. The pressure remains the same.
The flow rate of water through a 2-inch pipe at 100 psi can be estimated using hydraulic calculations. Generally, a 2-inch pipe can flow around 40-50 gallons per minute (GPM) at that pressure, depending on factors like pipe length, fittings, and friction loss. For precise calculations, it's best to use the Hazen-Williams equation or consult flow tables specific to the pipe material and conditions.
