How to save on cost and wastage

It is all.about numbers

I guess I have binged watch that program on Amazon too much,you know the one .The one about an FBI and mathematician called numbers of nu3bers given its exact title

Well just recently this has got me thinking during a lapse period at work .

How can simple maths be applied in my industry or else where.

I recall.my college days in South London polytechnic walking up.and down a yard with a heavy back pack sprayer on my back dressed up like a Martian

And that was after we. Told how to calibrate the back pack

So here begins the first lesson

How to calibrate a chemical..

1. Fill.your knack sack with water and Mark out area of 100 square yards

2. Walk.up.and down pumping the water out untill you covered the whole area

The maths bits

1. Measure how much water is used up. By subtracting the water before (w b) ..from. How much has been left after ( w a) .to give you the total of how much too use

Example

A sprayer is filled up.to max of 10 litres of water

After ward the amount of water left is is 8 litres

There for 10 - 8 = 2

Only two litres was used up.for 100 square metres

Now that you know how much water covers a metre square you calculate how much is needed to cover your area

By dividing your whole area by the w a

Example

Whole area ( B )= 400 Sam

W.a = 100

Total = 4 litres

Now depending on the chemical instructions the dose is ideally 1:20 .(1 part chemically 20 p arts water for 100 square yards

To then work out how much chemical to add to the knapsack tank, divide the product rate L/hectare) by 10000 and then multiply by the area covered with a full knapsack.

- For example, using the knapsack sprayer above and a product that has a rate of 5L/ha the formula would be 5 divided 10000 multiplied by 320 which gives you 0.16L or 160ml.
