Bernoulli's Equation Example Problems, Fluid Mechanics - Physics

This physics video tutorial provides a basic introduction into Bernoulli's equation. It explains the basic concepts of bernoulli's principle. The pressure is high when the velocity is low and the pressure is low when the fluid flow is high. Also as the height increases, the pressure decreases. This video contains plenty examples of calculating the flow speed and the water pressure in different sections of a circular pipe where the height, radius, and cross sectional area changes. This tutorial also explains how to derive the formula for Bernoulli's equation using kinetic energy, potential energy, and mechanical energy.

    In the 3rd problem, the arrows for the direction of flow were assumed at the beginning and never reexamined which causes some confusion. The water must be flowing uphill (from c to a) because the direction of flow is always from high pressure to low pressure.

    For question 2, what is the distance between points A & B? Without the distance or the amount of time it takes to travel from A to B at 4 m/s, slope cannot be calculated. I am no expert on this topic, but it seems that a 10 meter increase in height over the span of 1 meter would yield a different result than a 10 meter increase in height over 10 Kilometers. Am I wrong? Did I miss something?
