Gases Mixing

AI Thread Summary

When two connected cylinders with different pressures are combined, the final pressure depends on their volumes and initial pressures. If the cylinders have the same capacity, the resulting pressure will equalize to 1.0 bar, assuming constant temperature. If the cylinders differ in volume, the final pressure can be calculated using the formula that accounts for the individual pressures and volumes. The discussion highlights the importance of knowing the cylinder capacities to determine the final pressure accurately. Understanding gas laws and pressure dynamics is crucial in such scenarios.

Hi

Suppose there are two cylinders / vessels.
In one cylinder the pressure is 1.5 bar & in other 0.5 bar.If both cylinder are connected internally through valve connection, what will be the final pressure in both? explain

You did not mention if the two cylinders are of the same capacity. If so, the pressure is 1.0 bar in both provided that the temperature is unchanged.

Let the two cyclinders have different diameters, D and d

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:

Thread 'A cylinder connected to a hanged mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
