Fluid Mechanics: Topic 8.7 - Minor losses in pipe systems

Note: The equation presented at 1:48 is used for turbulent flows. For laminar flows, (which occur less frequently), the equation for the minor losses is K (Vavg mu / D gamma).

Thanks, I've been looking for this concept for more than 4 days. My assignment submission deadline is today midnight 😆😆😆

[@CPPMechEngTutorials]

Just in time.

Nice and detailed explanation. ❤️ from 🇮🇳

[@CPPMechEngTutorials]

Thanks!

at 3:40, why wouldn't the velocity change by bernoulli's eqn since there's a difference in elevation

[@CPPMechEngTutorials]

speed is related to conservation of mass. If the fluid density and area do not change at the inlet and outlet, the average speed would not change.

[@user-hs4dr7tg1u]

thank you

[@AeroCraftAviation]

But even if the pipe diameter does not change, we will still have velocity change due to friction causing pressure losses, right?

[@CPPMechEngTutorials]

If the pipe diameter does not change, the average speed will be constant throughout the pipe. The pressure due to frictional losses will decline along the pipe.

nice channel!

great! thanks!

[@CPPMechEngTutorials]

Glad it helped!

I ran some plumbing in my house and noticed a loss in pressure , somebody told me to replace all 90 degree elbo with 2 45 for better flow

How to find coefficient of bend K

[@CPPMechEngTutorials]

You have to look it up somewhere.
