Hi, could you please help me clarify #5 the NSB. for ideal fluid and real fluid you have both velocities = 0. I thought I heard you say something different. Please clarify. Thank you.
@@SealSchool hi, thank you for your prompt reply. This is what I understood from the video. Please help me check if I understood it correctly. So for ideal fluid, its viscosity =0 so does that means the fluid itself has its own steady velocity that continues to flow forward. the zero velocity on the slide is only talking about the point of contact between the fluid and the boundary? Since we assume that ideal fluid does not make any contact with that point on the surface hence there is not velocity of the surface goes against the ideal fluid flow. As for real fluid, it has viscosity hence its flow will not be smooth due some resistance in its own fluid property Hence, it will make some contact with the boundary. This is where I got confused because of the zero velocity you had on the slide. I thought since they real fluid makes contact with the boundary, hence we should see some velocity of the surface against the fluid. Could you help clarify again the zero velocity for both types of fluids? Many thanks.
@@valcheung5747 If you are having trouble understanding this think it in some other way. Ideal fluids have zero viscosity, hence the Reynolds Number for Ideal fluids is infinity so the No Slip Boundary condition is not applicable for an infinite Reynold Number !!

Dont use background in a class
very nice video lecture very effective and very short and sweet.

Make videos on mass transfer operation please!!
Can ideal fluids be shown practically?
Very helpful for last Time revision for hsc exam ❤️🙏🏻👍🏼
All the best to you !!
Thanks sir
Thanks for post this video😊
Good luck and all the best
Good Job
Also Subscription
Thank you, all the best :)
please i need help examples of ideal fluid
Ideal fluid is just a concept
Fluids found in nature are real fluids :)

For Ideal Fluids ,the viscosity is zero hence the no slip boundary condition is not valid :)
