Dear Kunduru Srinivasa Reddy you can read many articles and get more information. Here i give you the link of two articles where you can obtain several model to estimate some fuel properties such as kinematic viscosity, density, flash point, calorific value, cloud point and pour point.

Thank you so much...

Dear KS Reddy,

You can also use an online portal: http://www.brteam.ir/analysis/

where you can feed the composition of the blends you are working on and it will calculate (a prediction tool) its properties.

I hope it would be of help to you.

You can go through my paper to have the formula and compare it with the biodiesel from algae that I produced. Links are as follows-

I think the best way is to conduct experiments to determine this properties. However, you can also use well validated models.

I have used the super position theory.

please refer to:

you can use superposition theory according to the weight of each components
