Your garden ponds. Good garden ponds designs need pond volume information.
Water volume calculations or measurement for your garden ponds is often necessary. This is especially important to assist in choosing pumps for garden ponds. All garden ponds with few exceptions need to circulate water.
You will need to know the volume of garden ponds under the following particular circumstances:
Pump specification for garden ponds design
Treatment of garden ponds under differing pond water conditions - eg blanket weed excess.
Addition of medicines to garden ponds. Then accurate volume knowledge is critically important
The really clever people measure the volume of their garden ponds accurately when they first fill them - or they specify it in the garden ponds designs or they buy preformed garden ponds where the volume has often been pre-determined. They then keep that information in a safe place. If not then this is how to measure the initial volume when filling the garden ponds for the first time. Do record and keep safe this knowledge about your garden ponds.
Using a hose pipe to measure your garden ponds volume
The garden hose is turned on and the amount of time taken to fill a 10 gallon or other known volume container is taken.
The garden ponds are then filled without changing the position of the hose tap.
The amount of time taken to fill the garden ponds is recorded and then the volume is calculated as follows:
Time to fill garden ponds is divided by time to fill fixed volume container. This result is then multiplied by the volume of the container. For example time taken to fill a 10 gallons container is 1.8 minutes. Time taken for garden ponds filling is 23.9 minutes. Then garden ponds volume is 132.7 gallons ( 23.9 divided by 1.8 multiplied by 10).
To calculate the garden ponds volume.
It is very difficult sometimes to do this with great accuracy but for most garden ponds it is normally not critical if we are 10% or so out.
For regular shaped garden ponds based upon squares and rectangles the calculation is simple using fixed formulae. More complex regular shaped garden ponds such as trapezoid, triangular, hexagonal and so on are included on the FREE calculator link above as also are the calculations for the simple round, square, rectangular shaped garden ponds also
Coping
with Irregular shaped garden ponds Irregular shaped garden ponds are
calculated using "squares". This is a bit tedious done manually but with the
help of the calculator programs above is greatly simplified and the results for
your garden ponds volume are very accurate when care is taken.
I have read your book with interest and have found it most interesting. I wish I had read it before constructing my pond Gordon Powell, seaview@scottburgh.co.za
I read your book cover to back cover last night ., Excellent, this is just what I was looking for. It is hard to find such a comprehensive collection of information in one place. I have been searching the web for about 4 months. Brett Salavoy, Brett.Salovy@za.didata.com
