In transesterification reaction, we use molar ratio for biodiesel production. But at micro level or in microdevices flow rate is an essential factor. People calculated the flow rate of oil and alcohol from their ratios. Such as 6:1, 12:1 oil to methanol ratio.
I did not get how they calculate the flow rate of oil and methanol.
For example:
5:1 4.41 ( oil ml/h) 1.43 (ethanol ml/h)
14:1 3.06 (oil ml/h) 2.77 ( ethanol ml/h).
I did not get how the calculate the amount of oil and ethanol.
It's good question !!! You may refer to the textbook "Introduction to Fluid Mechanics," by James A. Fay, MIT press. Good Luck
You cannot get flow rates from ratios - very simply, 10 liters/s of oil, and 1 litre of alcohol as well as 20 liters of oil and 2 liters of alcohol have the same molar ratio of 10! Unless you know the total flow rate or one of the flow rates, you cannot get the flow rates!
Is it possible for You to measure the flows? What are the viscosity of the individual compounds?
Henrik Romar i can control the flows. I am using methanol and vegetable oil and oil viscosity vary with respect of temperature.
