He is not just highly knowledgeable but also he actually knows how to present things perfectly in front of people..well this makes learning way too easy...respect❤

[@CPPMechEngTutorials]

Maybe we should make it more difficult. :)

[@Xev729]

Beautiful!

[@husnainhyder6713]

I love everything related to Pomona county Well the number#1 thing is Cal Poly Thanks a lot for helping people in need

[@maximilianoromero8008]

Muy buen video, me sacó un montón de dudas, que agradecidos deben estar de tener ese profesor adelante. Saludos de Argentina

[@CPPMechEngTutorials]

Gracias

[@husnainhyder6713]

I usually left this part of fluid mechanics But Dr Biddles made it interesting. He is truly a Paul Newman of fluid mechanics

[@user-jg5zw2ho6q]

great video

[@sumitzanje5207]

Really great.

[@CPPMechEngTutorials]

We are glad you enjoyed the video.

[@yokeleetan8525]

just want to comment that w and rpm shares same dimension that is sec -1. and it also explains well affinity law of pumps and fans.

[@ammarsyaf3035]

I suppose the let repeating variable should be w, Q, & D right?

[@drnwanneoguama1415]

I like ur teaching

[@CPPMechEngTutorials]

Thanks!

[@ensea-ensenandoseaprende4961]

GRACIAS POR COMPARTIRLO !! EXCELENTE CLASE.

[@devkiwboy]

Thanks for the great video. Can you explain why you chose impeller diameter as the only characteristic independent variable relating to the pump in question? Was there some reasoning behind that you could explain please? Thank you again.

[@AshrafAliK7]

That was really helpful thank you Sir! ❤️

[@CPPMechEngTutorials]

Our pleasure

[@EngLhag]

Could I use these same equations for positive displacement pumps too (from any type)?

[@yokeleetan8525]

dont see how it can be applied for pd pumps. the affinity law applies to same family of pump, ie the relationship between the pump impellers to volute and diffusers are similar, only pumps are scaled. thus having data for one pump can predict similar scaled pumps.

[@NzeDede]

hi I'm really grateful for the videos and the further illustration within the subject of fluid dynamics. My question is, using the similarity law, as in this case, can I still predict the performance of a similar pump whose speed and impeller diameter have been changed all together purely using those same test data?

My lecturer should be ashamed when watching this gentleman presenting the same concept but, actually making sense out of it. Unlike my lecturer, whom you would feel asleep listening to his uselessssss lectures
