Well say you take a mechanical advantage piston setup or or the footprint of a column, reducing the area on one of the pistons or at the end of the column will cause a rise in pressure at that point. Thats what I'm used to at least. Now in my mind when I picture a nozzle I see a volume of fluid...
I don't know why, I'm clearly wrong on that thought so I'm looking for insight to set my thought process straight on the matter. Maybe its just been beaten into my head to long that you increase pressure when you reduce area. What you say about about the flow seeking lower pressure does however...
Hi There,
Im studying thermodynamics at the moment and there's one statement about nozzles that I just haven't been able to understand. In my mind when a fluid exits a nozzle it would have a higher pressure than the inlet. Could someone please explain in what sense the pressure of a fluid drops...
Hey there,
In my statics class we're just finishing up moments of area or moments of inertia as they're being called. I can do the math and figure them out just fine but I have no clue what I'm actually finding! What is it? I am having trouble actually conceptualizing what it is that I'm...
Perfect thank you for the help. And yes there's the friction of collision before the surfaces reach the same speed, bearing friction, moment upon the axle, and air resistance.
So my angular momentum will be conserved even though I'm going from a disc rotating about its centre of mass to a system of the ring and disc not rotating about it's centre of mass?
Following that I'd just calculate L of spinning disc with initial ω, then subtract L of disc after collision...
Homework Statement
These are the pre lab tasks for my upcoming lab. Find the theoretical value for moment of inertia for a ring with off axis rotation using parallel axis theorem and outline procedure to obtain experimental value of I.
During the lab we will be using a rotating platter with a...
