THE | | | REVISED PLANS SPECIFY A TDH OF 30FT FOR THE 1 HP | | | FEATURE PUMP SYSTEM AND 56 FT FOR THE 1.5 HP PUMP | | | SYSTEM. SUBMIT SIGNED AND SEALED CALCULATIONS SHOWING | | | HOW THESE TWO TDH WERE DETERMINED. THERE WERE NO | | | CALCULATIONS SUBMITTED INDICATING HOW THE TOTAL DYNAMIC | | | HEAD FOR EACH OF THE SYSTEMS WAS DETERMINED. UNLESS THE | | | TDH CALCULATIONS ARE SUBMITTED THE MAXIMUM CAPACITY OF | | | THE PUMPS WILL BE USED TO DETERMINE THE WATER VELOCITY | | | IN THE PIPES. | | | | | | 2) ANSI/APSP-7 2006 SECTION 4.4 LIMITS THE WATER | | | VELOCITY IN BRANCH SUCTION PIPING TO A MAXIMUM OF 6 | | | FEET PER SECOND WHEN ONE OF A PAIR IS BLOCKED. THE | | | TABLES ON SHEET 3 OF THE REVISED DRAWINGS LIST THE FLOW | | | AND VELOCITY WITH BOTH BRANCHES UNBLOCKED. HOWEVER, THE | | | WATER VELOCITY IS LESS THAN 6 AT THE FLOW RATES/GPM | | | SPECIFIED. | | | | | | ROBERT MCDOUGAL | | | BLDG. PLAN REVIEW | | | (561)805-6714 | | | [email protected] |
