What is the material derivative? 【Basic of fluid mechanics】 

If you study fluid mechanics, you’ll definitely encounter the idea of the material derivative. However,
【Question 1】Is the material derivative of a velocity an acceleration of fluid? If so, what’s the difference from an ordinary acceleration?
【Question 2】What’s does it mean if you partially differentiate a velocity with respect to time? Will it be different from an acceleration?
If you have those kinds of questions above, this video will help you understand what the material derivative is.
