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
 
Physics news on Phys.org
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 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging 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...
