Turbulent friction coefficient over a plate

AI Thread Summary
The discussion focuses on calculating the turbulent friction coefficient (Cf) over a plate using the equation Cf=0.0577(μ/xρUm)0.2. The user successfully completed parts a) and b) but is uncertain about their calculation for the first part, which yielded a CDf of 0.00421, differing from the expected value of 0.00263. They reference a document indicating that CD represents an integrated average of local Cf values over the surface area, suggesting further steps are needed after integration. The conversation highlights the importance of correctly applying the integration process to obtain accurate results. Understanding the relationship between local and average friction coefficients is crucial for solving the problem accurately.

Cf=0.0577(μ/xρUm)0.2

The Attempt at a Solution


I've managed to do parts a) and b), however I don't believe my attempt at the first part is correct as I am using a different Cf than the value used in the mark scheme.

The expression I made for the first part is, 0.0577(μ/ρUm)0.2[x0.8], with limits L and 0.
This gave me a CDf of 0.00421, but it should be 0.00263:oldconfused:.

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 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...
