As opposed to 'wow, there goes prolific brad'? Just out of curiosity, is there supposed to be a comma between amazing and brad? Or is there none there intentionally.

Once I put gravity back into the formulas and used feet and seconds only, I gained a tremendous amount of sprinkler calc confidence-- now I can use derived formulas and look-up tables most of the time- but am able to get from one thing to another logically in any rare situations. -----Original Message----- From: Thom [mailto:[email protected]] Sent: Monday, September 20, 2010 2:33 PM To: [email protected]; [email protected] Subject: RE: Monitor nozzle Yeah besides that .98/.97 really only works in the theory world. When the fitter drops the nozzle installing it, do you think he'll ever admit it's egg shaped with that big gouge in it cause he dropped it. Especially if no one notices. What's it's CD now? .821365798213465????? Seriously, how many of us were staying up at night this weekend, worrying about the .97 vrs .98? Your nozzle must be fundamentally different :) --And if you just have Q, convert to ft^3/sec, convert 1.75" diam to ft^2, divide 1st by 2nd to get ft/sec, h=v^2/2g, P= h x .433. (coefficient of discharge for monitor noz might be about .98, g=32.2 ft/sec^2)-- This means the coefficient of discharge is .97 And if you just have Q, convert to ft^3/sec, convert 1.75" diam to ft^2, divide 1st by 2nd to get ft/sec, h=v^2/2g, P= h x .433.
