Bernoulli's fluid flow in a tube [desperate]

AI Thread Summary
The discussion revolves around a student struggling to solve a Bernoulli's equation problem two days before a final exam. They express frustration over not being able to match their answers with the provided correct solutions. Key points include the necessity of knowing the diameters of the pipe and the exit pressure to solve the problem accurately. The conservation of mass is highlighted as a crucial step to determine the final velocity of the fluid, assuming incompressibility. The conversation emphasizes the importance of these parameters in applying Bernoulli's principle effectively.

This problem cannot be solved without the diameters of the pipe, or the exit pressure. To be honest, I'm not sure what you could have tried to get an answer.

IF you have the diameters. You use the conservation of mass to obtain the final velocity, assuming the fluid is incompressible, so mass flow is constant. From there, you have all but one (exit pressure) term in Bernoulli's.

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'

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...
