Understanding Bernoulli Loss in Fluid Dynamics

AI Thread Summary
Bernoulli loss refers to the energy dissipation in a fluid due to turbulence, which is not accounted for in the standard Bernoulli equation. This loss necessitates the inclusion of a head loss term to accurately reflect the energy conservation principle in fluid dynamics. The standard Bernoulli equation does not consider viscous dissipation, leading to potential inaccuracies in calculations. Understanding Bernoulli loss is crucial for analyzing fluid behavior in practical applications. Accurate modeling of this phenomenon is essential for effective fluid dynamics analysis.

"Bernoulli Loss"

Hi,

I am reading a fluid dynamics paper about dissipation due to turbulence in the fluid causing "Bernoulli loss". What exactly is meant by this? The Bernoulli principle concerns energy conservation. So, does Bernoulli loss simply refer to a loss of energy within the fluid (due to energy dissipation)?

Thanks

It means that when applying the Bernoulli equation to the fluid, you would need a head loss term to account for viscous dissipation because it is not covered by the standard Bernoulli equation. That isn't a very common term though.
 

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Beam on an inclined plane'

Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
