      Version 2

      After some recent discussions I have learned a little more. I have included this new information in version 2.

      As it's too large to load myself Justin will have to do it so please be patient till he gets it set up.

      You're welcome.

      Hopefully everyone is downloading the latest version and deleting the old one.

      Lost on draw down calculation

      Apologize in advance for being dense
      I am struggling with the "How to calculate draw down" section of Garrett's Primer.

      I am fine with calculating the friction portion. However, can anyone explain how the ' 2.76" ' figure in his ' Draw down 3" ' example was derived?

      I really want to make sure I understand this calculation.

      Thanx in advance,
      Alan

      Yeah, this confused me for a while as well. Here's the answer:

      Based on the total head calculation on the middle of page 31, we see that the straight pipe plus all the fittings yields the equivalent of 38.1' of pipe.

      At 3000 gph, you have 0.6' of head for every 100' of 3" PVC line (from the first chart on page 14).

      To find the resistance caused by that 38.1 feet of pipe, you multiply the 0.6' (per hundred feet) times 38.1/100.

      38.1 feet of pipe X (0.6 feet resistance/100 feet of pipe) = 0.2286 feet of resistance = 0.23 feet resistance

      Now for the trick:

      0.23 feet of resistance X (12 inches/1 foot) = 2.76 inches of resistance!

      You're converting feet to inches. Incredibly simple, but it completely threw me for a loop as well...

      Maybe he'll put a note in the next version to clarify this.

      Thanks Webted!

      I knew it had to be something simple. I guess I have been trying to absorb so much info my old processor overloaded.
