Hello Friends,

I have a base stock oil that is relatively viscous (at 100 degC 26 CSt, at 40 degC 400 CSt). I need to heat it up so a filling machine (18 L canisters)  can fill. No problem during the summer, only winter months are challenging and assuming 10 degC( at that temp about 5000CSt) material temp, I need to heat it up to 40degC for the machine. Calculating required energy to heat the oil using Q=mCpdt doesn't help since the material is viscous and without mixing it, energy dissipation is slow so if heated it gets liquid enough next to the walls of the tank or a heating element first and then further away. So i am looking for some sort of correlation between viscosity and specific heat so A better and more reflective calculation can be made for a heating element or a double jacket vessel.

Up till now I used to fill the canisters by manual labor but the demand for the product increased and I cant devote someone only for this product, It makes no sense.

Thanks
