What are the viscosities of vegetable oil, air, water, copper sulphate - CuSO4, salt and sugar?

I need the viscosity for each individual material at 25 degrees celcius please.What are the viscosities of vegetable oil, air, water, copper sulphate - CuSO4, salt and sugar?
The viscosity of water at 25掳C is


畏 = 8.91脳10-4 Pa路s





The viscosity of air at 25掳C is


畏 = 1.74脳10-5 Pa路s





The viscosity of vegetable oil. cant be specified generally. Vegetable oil is a mixture fatty acids. There are several different types of vegetable of different composition. And of course the viscosity changes with compostiion.


Even for a particular oil like olive oil or palm oil the the compositions varies of a smaller range due to growing conditions, way of processing the vegetables, etc.


So just two examples i know:


olive oil


畏 鈮?1脳10-2 Pa路s


palm oil


畏 鈮?3脳10-3 Pa路s





Copper sulfate, salt and sugar are crystalline solids at 25掳C. Crystalline solids don't have a viscosity because they don't flow.
