flow rate loss through 10 feet of 3/4" k copper
flow rate loss through 10 feet of 3/4" k copper
(OP)
Hi Guys have a wired question to ask.
need to know what the flow rate would be for the following:
Main Line 10"
Service line first 10 feet to curb valve is 3/4"
rest of service to house is 1-1/4" for 55 feet.
what is my actual flow rate at the end of the 1-1/4" line b/c of the first 10 feet being 3/4"
everything is k copper and static pressure is 85 psi at the end of the line.
totally stumped on this one

and this is a water service line from the town supply
thanks for your help in advance

8 ft/sec will give you approximately 11 gpm with a headloss of around 6-7 psi.

Not sure what is the practicality of this theoretical calculation.
If you exceed the recommended velocity of 8 ft/sec in the copper tubing, then the copper tubing will corrode away in a short time.

thank you for your real work answer, i noticed on the sheets you provided that it has an actual 50 gpm rating but that's with an open flow and no resistance. i think i will design the system around 20 gpm and be on the safe side.
thanks for all the input guys.
