Fluid Dynamics Pressure Difference

AI Thread Summary
To find the relative pressure difference in a U-shaped test tube displacing oil with a density of 0.85 g/cc by 25mm, one can calculate the weight of the oil column on the high side compared to the low side. This involves determining the height difference created by the pressure and converting it to weight. Dividing this weight by the area of the base of the oil column will yield the pressure difference. Understanding the relationship between pressure, density, and displacement is crucial in fluid dynamics. Accurate calculations are essential for practical applications in fluid mechanics.

if you are given that a pressure displaces an oil (density = .85g/cc) 25mm in a contraption that looks like a long u shaped test tube, how would you find the realitve pressure difference?

I'd probably try to figure out the weight of the on the high side that was higher then the oil on the low side, and divide that by the area of the base of the column of oil
 

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

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 '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...
