Fluids Mechanics, finding height in the piezometric tube

AI Thread Summary
In fluid mechanics, the discussion focuses on determining the height h in a piezometric tube and the velocity V at a nozzle for a large open tank with water flowing through a pipe. The scenarios analyzed include a blocked nozzle (a = 0), a nozzle area equal to half the pipe area (a = A/2), and a nozzle area equal to the pipe area (a = A). The application of Bernoulli's principle is suggested to solve for the height and velocity in each case. The discussion emphasizes the relationship between flow area and resulting fluid dynamics.

A large open tank, shown below, contains water at a height H. The water is allowed to flow out through a pipe whose cross-sectional area is A. The pipe has a nozzle at the end, whose area is a. Assuming frictionless flow, determine (i) the height h to which the water rises in the piezometer tube, and (ii) the velocity V at the nozzle, for the following three cases:
a = 0, i.e., the nozzle is blocked and no flow is allowed.

a = A/2

a = A

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Beam on an inclined plane'

Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
