For your records <br /> the details of that test are as follow: <br /> Water was flowed from the hydrant on Shadywood Road at the southern <br /> boundary of the Gray FresMwater Center. A single 2- 1/2 inch butt was <br /> opened and a pitot reading of 50 psig was recorded. This equates to a <br /> flow rate of 1185 GPM. <br /> Static and residual pressure was measured at the hydrant located <br /> centrally in front of the Gray Freshwater Center building, close to their <br /> water connection. Static pressure was recorded as 58 psig and the <br /> residual pressure during the flow was measured at 50 psig. <br /> For your convenience I have attac�ed a copy of the graphic representation of this water <br /> supply. Should you have any queStions or wish to discuss this test in greater detail <br /> please feel free to call me at 612/742-7274. <br /> I also ask that you convey our tharhks to the finro gentlemen from your department for <br /> the assistance they gave us during the test. <br /> Very truly yours, <br /> �� P-�� <br /> B.
