Solution

The first statement is true. The higher the water level in the reservoir, the greater the potential energy of the water. When this potential energy is converted into kinetic energy as the water flows down the intake pipes, the kinetic energy will be greater.

The second statement is also true. The speed of the water flowing in the intake pipes is determined by the pressure difference between the water at the reservoir level and the water at the intake pipes. The higher the water level, the greater the pressure difference, and thus the greater the speed of the water.

The third statement is false. As explained above, the reservoir water level does make a difference to the kinetic energy of the water in the intake pipes.

The fourth statement is also false. The higher the water level in the reservoir, the greater (not lower) the kinetic energy of the water flowing in the intake pipes.

Water behind a dam has a certain amount of stored energy that can be released as the water falls over the top of the dam. It may be enough energy to turn a mill wheel or an electricity-generating turbine. Choose the term that best describes the type of energy stored in the water at the top of the dam.Group of answer choicesChemicalPotentialKineticRadiant

Water is pumped through an inclined pipe. The pressure, velocity, and datum at the pipe inlet are 10 bar, 17 m/s, and 0 m, respectively. The pressure, velocity, and datum at the pipe outlet are 5 bar, 21 m/s, and 4 m, respectively. Assuming g=10 m/s2 for convenience, determine the change in the Bernoulli head in m for this section of the pipe. The kinetic energy correction factors may be approximated as 1.0 for simplicity.
