Formulas for Sizing a Liner |
|
WIDTH + (DEPTH X 2 ) + (OVERLAP X 2 ) EXAMPLE- FOR A FINISHED SIZE OF 8 X 10 X 2 DEEP- 8+(2X2)+(1X2) 8+4+2= 14 10+(2X2)+(1X2) 10+4+2= 16
LINER WIDTHS COME 10 15 20 AND 25 POND LINER NEEDED WOULD BE 14 X16 BUT YOU WOULD BUY A 15 X 16 15 X 16 = 240 SQUARE FEET 240 X .68 = $163.20 FOR THE LINER
DONT FORGET TO GET ENOUGH EXTRA
FOR UNDER YOUR WATERFALL! FORMULA TO FIGURE OUT GALLONS IN POND FOR SQUARE AND RECTANGLE PONDS - LENGTH X WIDTH X AVERAGE DEPTH X 7.5
FOR ROUND PONDS - DIAMETER X DIAMETER X AVERAGE DEPTH X 5.9
FOR IRREGULAR SHAPED PONDS - LONG DIAMETER X SHORT DIAMETER X AVERAGE DEPTH X 5.9
EXAMPLE - 8 X 10 X 2 POND 8 X 10 = 80, 80 X 2 = 160, 160 X 7.5 = 1200 GALLONS
TO FIGURE OUT GPH TIME IN SECONDS HOW LONG IT TAKES TO FILL A ONE GALLON CONTAINER. DIVIDE THE SECONDS IT TAKES BY 3600. EXAMPLE - IF IT TAKES 6 SECONDS TO FILL THE CONTAINER IT WOULD BE 3600 DIVIDED BY 6 = 600. IT IS 600 GPH.
FORMULA FOR WATTS AND KILOWATT HOURS TO FIGURE OUT HOW MUCH SOMETHING WOULD COST TO RUN IF YOU HAVE THE WATTS- WATTS DIVIDED BY 1000 = --- --- X HOURS USED PER DAY = --- KILOWATT HOURS. AVERAGE COST OF .11 PER KILOWATT HOUR- .11 X --- = AMOUNT IT WILL COST.
EXAMPLE - 300 WATTS DIVIDED BY 1000 = .3 .3 X 24 HOURS = 7.2 KILOWATT HOURS .11 X 7.2 = .79 A DAY TO RUN.
