    pour point and molecular weight of crude oil!

    hi 25362, infact I have sp.gravity and viscosity of crude oil and I need to use equations if it is possible to predict the pour point and molecular weight and make comparison between the two results. I hope my question is clear. thanks

    Cooling rate for WAT

    hello to all, By using differential scanning calorimetry which perfect cooling rate does it use for measuring wax appearnce temperature, for measuring melting poing, 10°C/min is common used. from my experience WAT affect by changing the cooling rate (e.g petroleum product), however some crude...

    Dynamic viscosity @ kinematic!

    thanks 25362 for ur reply, however as you know there are different values of dynamic( minimum and maximum ). so what do you think the perfect value as represent the all.

    Dynamic viscosity @ kinematic!

    hi all, I am working on rotational viscometer to measure dynamic viscosity and I have to use just one value to calculate the kinematic viscosity, but in this case I've already got many values of dynamic viscosity at shear rate range from 0 -1000 s-1. my question now is can I use the only first...

    Flow rate and viscosity testing - preferably in Hong Kong or China

    Hi to all, I have to points here: 1) I am working on the rotational viscometer to measure dynamic viscosity through relation ship between shear rate and shear stress, if I want to calculate kinematic viscosity which value I should take for my calculation because I have many point lets say from...
