One cubic metre of water |
|
= 1000 litres |
To calculate how many litres a round tank or drum will hold:
To calculate the volume of a cylinder shaped container in litres.
Measure the container using a metric ruler and note the sizes in parts of a metre.
For example a 150mm radius = 0.15 metre.
A height of 600mm = 0.6 metre
Method is 1) 3.142 x ( radius x radius)
2) Multiply the answer by the height of the container
3) Multply that answer by 1000.
4) The result is litres.
Dilution ratio formula:
1 divided by the ratio x the container size = volume of cleaning chemical to mix with water
| Example: |
Dilution Ratio of 1:80
1 divided by 80 = 0.0125
x 1000 = 12.5mls of chemical per litre of water |
If you dont want to do the math, then as a rough guide, one half cup = about 125mls. So if that is the only measure available then 1/2 a cup of chemical mixed with 10 liters of water in a bucket will be at a mixing ratio of about 1:80
Floor Finish:
A general guide for the coverage of most quality brands of floor polish would be 50 to 60 square metres per litre, per coating on regular vinyl floor coverings. Some stone or ceramic coverings will require more on the first 2 coats due to their porosity.
Floor finish products imported from USA may have square feet per US gallon coverage on the container label. To convert to square metres per litre use the following formula.
Square feet cover x 0.0929 then divided by 3.845 = square metre cover per litre |
