General Energy Equation: Pump and Turbine Analysis

[@tommyminahan3136]

I really appreciate all these videos you've created. I'm sure a lot of time and effort has have been spent crafting these perfectly direct, clear, and straight to the point instructional videos. Thank you so much

[@FluidMatters]

Thanks for the kind words! Best of luck with your studies.

[@joeykoscal2275]

honestly you are an amazing Instructor! I wish I was taking your course

[@FluidMatters]

Thanks. Best of luck in your studies.

Thanks for this lecture Dr. David. That's really helpful.

at 28:03, why we used same volumetric flow rate in section 1 for section 2 to find velocity?
I know that after turbine velocity & pressure will drop therefore volumetric flow rate will also drop.
Thank you for everything your videos help a lot and please help me to understand my question.

[@FluidMatters]

Thanks for the time marker. That helps. This is a hydraulic turbine. Liquid water is the working fluid. Liquid water is incompressible i.e., density is not a function of pressure and thus, constant. So, both the mass flow rate and volume flow rate will be a constant at any point in the system, because rho=constant.

thankyou so much

thank youu 🤩

[@rubarmahmud334]

reference of this question??plz ?

[@FluidMatters]

Sorry, I can't recall... This is an old one. I've been teaching fluid mechanics for 20+ years. It's from one of the old "classics".

[@FluidMatters]

Found it: This is an end-of-Chapter problem in Munson, Young and Okiishi, Fundamentals of Fluid Mechanics, 2nd Edition, 1994, Wiley
