How Can I Calculate the Pressure Loss Coefficient of a Diffuser?

AI Thread Summary
To calculate the pressure loss coefficient of a diffuser, it's essential to consider the dimensions, length, scale, and conical degree of the diffuser. The equation provided, 0.4 x 1/2pv^2, can be used to estimate the resistance in pascals, where p represents air density, approximately 1.2 kg/m³. Bernoulli's principle may not yield accurate results without proper parameters. Accurate calculations require specific measurements of the diffuser's geometry. Understanding these factors is crucial for determining the pressure loss coefficient effectively.

Hi,
I want to calculate the pressure loss coefficent for a diffuser but I can't find the equation. I tried with bernoulli but I don't get it. I've read that the coefficient depends on the length the scale and conical degree of the difuser?

Can you help me?

thank you!

hi,

Without the dimensions i can't calculate it properly, but 0.4 x 1/2pv^2 will more than cover the resistance in pascals.

p= air density which is approx 1.2 kg m^3
 

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...
