| | |
| | NOTE - A COMPREHENSIVE REVIEW COULD NOT BE DONE AT THIS |
| | TIME AND ADDITIONAL PLAN REVIEW COMMENTS MAY BE |
| | GENERATED UPON THE RE-REVIEW OF SUBMITTED CORRECTIONS. |
| | |
| | 1. PLEASE SHOW HOW YOU DETERMINE THE SIZE OF THE GREASE |
| | TRAP PRESUMING YOU ARE USING 14 LB. GREASE CAPACITY, |
| | (7) GALLONS PER MINUTE RATE FLOW THIS UNIT SHALL BE |
| | SIZED IN ACCORDANCE WITH THE SIZING REQUIREMENTS PER |
| | THE 2017 FBC SEC P 1003.3.4 AND TABLE 1003.3.4.1. |
| | |
| | 2. ISOMETRIC SHOWS ALL SINKS MANIFOLDED TOGETHER PLEASE |
| | SEPARATE PER THE 2017 FBC SEC. 802.1.1. |
| | |
| | EXAMPLE 8-2 |
| | ASSUME A SINGLE-FIXTURE INSTALLATION. SIZE THE GREASE |
| | INTERCEPTOR FOR A THREE-COMPARTMENT POT (SCULLERY) |
| | SINK, WITH EACH COMPARTMENT BEING 18 ? 24 ? 12 INCHES. |
| | |
| | 1. DETERMINE THE SINK VOLUME: |
| | ? CUBIC CONTENTS OF ONE SINK COMPARTMENT = 18 ? 24 ? 12 |
| | = 5,184 IN.3 |
| | ? CUBIC CONTENTS OF THREE SINK COMPARTMENTS = 3 ? 5,184 |
| | = 15,552 IN.3 |
| | ? CONTENTS EXPRESSED IN GALLONS = 15,552 IN.3/231 = |
| | 67.3 GAL |
| | 2. ADD THE TOTAL POTABLE WATER SUPPLY THAT COULD BE |
| | DISCHARGED INDEPENDENT OF THE FIXTURE CALCULATED ABOVE, |
| | INCLUDING MANUFACTURER-RATED APPLIANCES SUCH AS WATER |
| | WASH EXHAUST HOODS. |
| | 3. DETERMINE THE FIXTURE LOAD. A SINK (OR FIXTURE) |
| | SELDOM IS FILLED TO THE BRIM, AND DISHES, POTS, OR PANS |
| | DISPLACE APPROXIMATELY 25 PERCENT OF THE WATER. |
| | THEREFORE, 75 PERCENT OF THE ACTUAL FIXTURE CAPACITY |
| | SHOULD BE USED TO ESTABLISH THE DRAINAGE LOAD: 0.75 ? |
| | 67.3 GAL = 50.8 GAL. |
| | 4. CALCULATE THE FLOW RATE BASED ON DRAIN TIME, |
| | TYPICALLY ONE OR TWO MINUTES. FLOW RATE IS CALCULATED |
| | BY DIVIDING THE DRAINAGE LOAD IN GALLONS BY THE DRAIN |
| | TIME IN MINUTES. THEREFORE, THE FLOW FOR THIS EXAMPLE |
| | WOULD BE 50 GPM (3.15 L/S) FOR ONE-MINUTE DRAINAGE OR |
| | 25 GPM (1.58 L/S) FOR TWO-MINUTE DRAINAGE. |
| | 5. SELECT A HYDROMECHANICAL INTERCEPTOR WITH A RATED |
| | CAPACITY OF 50 GPM FOR ONE-MINUTE FLOW OR 25 GPM FOR |
| | TWO-MINUTE FLOW. |
| | |
| | WHEN RESUBMITTING PLANS PLEASE INDICATE THE REVISION & |
| | REMOVE ANY VOIDED SHEETS & REPLACE ANY PAGES AS |
| | NECESSARY. A TRANSMITTAL LETTER LISTING THE ORIGINAL |
| | REVIEW COMMENT NUMBER, WITH A DESCRIPTION OF THE |
| | REVISION, MADE, IDENTIFYING THE SHEET OR SPECIFICATION |
| | PAGE WHERE THE CHANGES CAN BE FOUND WILL HELP TO |
| | EXPEDITE YOUR PERMIT. THANK YOU FOR YOUR ANTICIPATED |
| | COOPERATION. |
