In the example problem, you mention that this problem has two πs, how do we conclude this? (and sorry for the flood of questions on many of your videos, my final is in just over a week and your videos are fantastic!)
You must go through the Buckingham Pi analysis of previous lessons to determine the number of PIs. Now I have a question for YOU. How did you get the Greek letter pi to appear in your comment? I have never seen that before in a TH-cam comment!
@@johncimbala Just because a symbol isn't present on your keyboard doesn't mean it can't be used! 𝝅 is a unicode character like any other character (I.e., letters in various languages, numbers, symbols like $%#+*^, etc). Specifically here I copy and pasted the 𝝿 (there are multiple versions) symbol from a quick Google search, but if you know the appropriate keyboard shortcuts you can easily insert pretty any character (if I remember correctly ).
Hello Sir, I got a different value for density and viscosity of water at 20°C based on the table in Cengel Textbook. Mine is 1.204 kg/m^3 for Density and 1.825x10^-5 for Viscosity. Does the ratio model affects the value of Density and Viscosity? Thank You
You are using the air table instead of the water table. I checked and my values are correct. Doing ratios as in this problem does not affect the properties of the fluids, which are independent of any analysis we do, of course.
