| 2012-10-31 09:46:36 | 2010 FBC | | | | | | DENIED BY PLUMBING | | | | | | 1) THE MAXIMUM FLOW RATE OF THE VARIABLE SPEED PUMP IS | | | REQUIRED TO BE USED TO DETERMINE THE WATER VELOCITY IN | | | THE PIPES. THE PENTAIR INTELLIFLO VS 3050 HAS A FLOW | | | RATE OF 145 GPM WITH 50' TDH AT THE MAXIMUM OF 3450 | | | RPM. THIS MEANS THAT THE VELOCITY OF THE WATER IN THE | | | 2-1/2" PIPING WILL BE 9.48 FEET PER SECOND. THIS | | | EXCEEDS THE MAXIMUM WATER VELOCITY OF 8 FEET PER SECOND | | | IN SUCTION PIPING ALLOWED BY FBC R4101.6. THERE IS NO | | | BRANCH PIPING BECAUSE A CHANNEL DRAIN IS SPECIFIED | | | RATHER THAN TWO MAIN DRAINS. THE WATER VELOCITY IN THE | | | 2" PRESSURE PIPING WILL BE 14.81 FEET PER SECOND WHICH | | | EXCEEDS THE MAXIMUM WATER VELOCITY OF 10 FEET PER | | | SECOND ALLOWED BY FBC R4101.6 IN PRESSURE PIPING. | | | PLEASE CORRECT. | | | | | | ROBERT MCDOUGAL | | | BLDG.
