Could anyone tell me what peat with a 70% moisture content would look
and feel like. I would appreciate any help


John


I found the answer and as no one in this group seems to know I will
explain.


You get completely dry peat and weigh it - say 100g.


You then add water and weigh it again. If it weights 150g it contains
50% water content. If it weights 170g it contains 70% moisture
content.


Simple!


Perhaps simple, but wrong. In your first example, if it weighed 200g,
it'd be at 50% water.

Well John

It is really important that i know this so could you explain further.
For 100g of dry peat what would it weight with 70% moisture content?

John


john, if 70% of the wetted peat's weight is water, then the dry peat
represents 30% or .3(x) = 100g where "x" equals the total weight.
Rearrange: x = 100g/.3 = 333.3333g

So you would have 3 1/3 times more water than peat in the final product.
