Comparing pressure losses in compressible flow between air and natural gas

AI Thread Summary
Experimental data on pressure losses in compressible flow was collected using air, measuring static pressure, total pressure, and total temperature upstream and downstream of an obstruction across various mass flow rates. The discussion centers on the feasibility of adapting this data for natural gas using theoretical principles and reasonable assumptions. Dimensional analysis is suggested as a potential method for this transformation. The focus is on ensuring that the adapted data remains applicable and accurate for natural gas. This approach could provide valuable insights into pressure loss comparisons between the two gases.

Hi! I have experimental data measuring losses across an obstruction in compressible flow which basically consists of static pressure, total pressure and total temperature upstream of the obstruction and the same variables downstream for a number of different mass flow rates. This data was collected using air. Now I was wondering if it was possible, using theory and some reasonable assumptions to transform the data so that it would be applicable if natural gas was being used instead of air. Thank you in advance.

This can probably done using dimensional analysis.
 

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...
