How Does Changing Height Affect Bernoulli's Equation Values?

AI Thread Summary
Changing height directly impacts the values in Bernoulli's equation, as an increase in height leads to a decrease in the pressure and velocity terms. The equation accounts for gravitational potential energy, meaning that as height rises, the energy associated with height increases, causing the kinetic energy and pressure to adjust inversely. Conversely, a decrease in height results in an increase in velocity and pressure. Understanding these relationships is crucial for applying Bernoulli's principle effectively. Overall, height variations significantly influence fluid dynamics as described by Bernoulli's equation.

It's just a simple question. How does the height effect the other values if the height increases or decreases.
What happens when the height increases and what happens when the height decreases?

Have you examined the full statement of Bernoulli's equation, including the height term? See: Bernoulli's Equation

In any case, as the height of a streamline increases, the other terms must decrease accordingly.
 
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...
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...
