I have 8 gallons of a mixed fuel. It contains 93% Methanol and 7% oil. I need to add 8% Nitro to this current blend.
-----------------------------
The new mixture will be 85% Methanol, 8% Nitro and 7% oil.
-----------------------------
How can I go about making this new blend and keep it to an even amount of gallons?
-----
Start::
Meth:: 0.93*8 = 7.44 gallons of Meth
Oil:: 0,07*8 = 0.56 gallons of Oil
----
Adding 0.8x nitro
-----
Final:::
Meth:: 7.44 = 0.85*(8+x)
7.44 = 0.85*8 + 0.85x
0.85x = 0.64
x = 0.75 gallons (amt. of Nitro to add)
-------
Note:: The resulting mixture will not have 7% oil because
you did not adjust the original amount of oil.
The resulting mixture will not have 8% Nitro. Your 8%
nitro has been dilluted by the Meth and oil.
