I just had my water service line (galvanized) replaced with 1 inch plastic from the town shutoff on my front lawn to my house. What a difference! I then had the town run a flow (velocity) rate test the next day which produced 5 gal/1.5 min. of rusty water. Essentially, the excavation crew had to ream out about half of the distance from the shutoff to the main across the street to give me any water pressure/volume flow at all. That put me on the town list to replace the galvanized feeder line from the main to my shutoff, which just got replaced Tuesday - another 1 inch plastic line. No more rusty water! Now the flow velocity rate is 5 gal/1 min measured on the top floor bathtub into a 5 gallon bucket, and I can even run more than one faucet at a time - eureka! What's my water pressure?
Is it possible to compute the water pressure (psi) from the velocity, or is there not enough other information? I haven't studied fluid mechanics in many years so I'm a bit rusty myself.
I really would like to know if there are any water pressure calculators out there that can tell me what psi to expect (40<=psi<=80)? I live on a hill cul-de-sac more toward the bottom than the top, across the street from a fire hydrant (which is the town's priority to maintain good water pressure from a public safety point-of-view), and the nearest town water tower is on another hill at least 1/2 to 3/4 mile away.
I suppose its the case that I should just schlep on down to the local Home Depot and spend $5 get a 100psi water pressure guage to measure it.
Also, if I measure it at the outdoor spigot (ground) level, what % drop in psi is there from that elevation to the 2nd (top) floor of my house - assuming 10 ft differential in elevation - 5%, 10%?
