What is the maximum water flow through a 3 inch fire hose?
To find the maximum flow you would need to know the maximum pressure. A typical fire nozzle pressure would be up to 100 psi with a diameter of 1 to 1.25 inches. The GPM would be between 300 GPM and 460 GPM through the nozzle. If it were simply a 3-inch pipe with an oversized pump, running at 100 psi with no nozzle, you could (in theory) move over 3,000 GPM through the pipe (ignoring friction loss). Even at 80 psi, a master stream through a 2-inch nozzle moves over 1,000 GPM.
What is critical velocity for 3 inch hose?
The critical velocity for a 3-inch hose depends on the fluid flowing through it. In general, critical velocity is the velocity at which the flow changes from laminar to turbulent. It can be calculated using the Reynolds number for the specific fluid and hose diameter.
What is the flow rate of water through .75 inch pex pipe at 40 psi in gpm?
The standard formula to calculate flow(GPM - gallons per minute) from a CIRCULAR orifice is:29.7 * (the square root of the pressure) * (the square of the diameter of the flow orifice)EXAMPLE using 3/4" Pex Pipe(actual I.D. of 3/4 PEX Pipe is .677") and 40 PSI pressure:29.7 * 6.325(sq. root of 40) * .458(the square of the I.D. 3/4" pipe) =A GPM of 86.03Note: You also need to account for fittings in the loss calculations; while minimal several fitting will make a difference.
What is the Flow rate of one fixture unit?
3 gpm
How many centimeters to 3 inch?
1 inch = 2.54 cm therefore , 3 inch=2.54*3=7.62cm hence, 3 inch=7.62cm
What is the speed of water coming out from a tap?
The average kitchen faucet will deliver about 2.5 gpm. Some will be more and some less.
What fraction is 3 tenth of an inch?
Three tenth of an inch is 3/10 or 0.3 times an inch.
How many square feet is a 3 inch by 3 inch tile?
1 sq foot = 144 sq inch 3 inch x 3 inch = 9 sq inch = 9/144 sq feet = 0.0625 sq feet
How do you type three quarters of an inch?
3/4 inch 3/4" 0.75 inch 0.75"
Can you make a triangle out of a 3 inch line a 2 inch line and a 6 inch line?
Yes. 3+2+6=11. If you divide 11 and 3, your answer is 3r2. You will have two 3 inch sides and one 5 inch side.
What is .3 of an inch in a fraction?
3/10 of an inch
How does water come out from a tap?
The average kitchen faucet in a house will supply 2.5 -3 gallons per minute at 50 PSI. That is an average hose working pressure in north America. A large bath faucet will supply 3 + gpm and a single lever bathroom sink faucet will be about 2 gpm.
