Is My Method for Calculating Pressure Difference in a Venturi Meter Correct?

AI Thread Summary
The discussion centers on calculating the pressure difference in a venturi meter, specifically using a setup with a 25cm inlet and a 15cm throat, where a manometer shows a 12mm mercury displacement. Key equations referenced include Bernoulli's principle, mass continuity, and the hydrostatic pressure formula. The user seeks confirmation on the correctness of their method for determining the pressure difference, as they have no access to answers from a past paper. Urgency is expressed due to an upcoming exam, highlighting the need for clarity on the calculation. The thread emphasizes the importance of understanding fluid dynamics principles in practical applications.

Homework Statement


Water flows through a venturi meter, with an inlet diameter of 25cm and a throat diameter of 15cm. The pressure difference is measured using a manometer, which displaces the mercury by 12mm on the throat side.


Homework Equations


Bernoulli's
Mass continuity
P=rho.g.h

Is this correct? I have no answers available as its from a past paper. My exam is tommorow and I would just like to clarify that the method I have used to find the pressure difference is correct.

Thanks.

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...
