In the diagram of a leaking tank, what do the variables represent?
H: Height of the water in the tank, v: Velocity of the water exiting the hole.
What are the differences between Power and Work?
Work: Energy transferred (measured in Joules). Power: Rate of energy transfer (measured in Watts).
What is the effect of increasing fluid velocity in a horizontal pipe, according to Bernoulli's principle?
A decrease in pressure.
What happens to fluid velocity when a pipe narrows, assuming constant volume flow rate?
The fluid velocity increases.
What is the effect of increasing the height of a fluid on its potential energy?
The potential energy increases.
What happens to the exit velocity of water from a hole in a tank if the water height is increased?
The exit velocity increases (specifically, ).
