Physics 34 Fluid Dynamics (5 of 24) Viscosity & Fluid Flow: Viscosity of Water

In this video I will discuss the viscosities of water with respect to temperature.

Next video in this series can be seen at:

I enjoy your lectures, they are short but concise. They are good for people can't concentrate for too long like me. I am recently doing ocean modelling but have problem with some basic concepts since my degree was not on physics. Thank you very much for the effort!

Are the units right for viscosity i feel the 'm' shouldn't be there

Hi, these lectures are wonderful and have helped me understand these concepts much better than my uni lecturer did. Thank you! Although, I am confused as to why the units in the table for viscosity are given as (m.Pa.sec) and then on the graph as (Pa.sec)? As they are also defined as (Pa.sec) in the last lecture. Thanks, Sophie! :)

Hi professor, at 1:12 you stated that the viscosity pattern as a function of temperature is typical for all fluids. However, for gases, which are considered as fluids, this pattern is a bit different, as the gas viscosity tends to increase with temperature. Thank you for your lectures, it is very helpful, concise and clear.

Really nice video! Takes me a short time and teach me a lot!

should we take kinetic viscosity at Y-axis as it shows the movement of molecules and dynamic viscosity (Pa.sec 10^-3) is a standard value?

Is this graph of viscosity vs temperature for water similar to that of other fluids ? What would be the difference graph for newtonian and non-newtonian fluids ?
