Hello Professor its a great lecture but I was hoping to get some clarification on the problem that you do at the end of the lecture. When I do the calculation I get a Gr= 8.31x10^8. I have done it several times I put g=9.81, B=361.9x10^-6, delta T=34, L=.15, and v= .7x10^-7. If Gr=(gB(Ts-T)L^3)/v^2 then I get 8.31x10^8 and if the pr is 4.62 wouldn't that push Ra=GrPr past 10^9 which would be turbulent? Thank you for your time your lectures are extremely helpful.

Thank you for the classes. They are helping me a lot!

I meant v=7x10^-7
looks like you are correct. my mistake. thanks for checking
thank you so much
Can any one mention the name of book....?
Looks like "Introduction to Heat Transfer" (Incoropera, et al), but not sure of edition
