Final answer:
The incorrect statement is C, as a water chute, rather than a catch-all, is used for directing a large volume of water. Bernoulli's Equation explains how constricting the opening of a garden hose with a thumb increases water velocity, allowing it to squirt further.
Step-by-step explanation:
The incorrect statement is: C. A water chute is used when the volume of water is too great for a catch-all. Typically, when firefighting, a catch-all is intended for situations where the water volume is substantial, and a water chute is used to direct the flow of water straight to the fire or another desired location. The water chute allows for a controlled direction of water, whereas a catch-all is more often used to collect or redirect water that cannot be managed by the chute.
In reference to Bernoulli's Equation, you can squirt water further by placing your thumb over the end of a garden hose because this action reduces the cross-sectional area of the hose opening, causing the water to exit with higher velocity. This is due to the principle that when the cross-sectional area decreases, the velocity of the fluid must increase for the flow rate to remain constant, and according to Bernoulli's principle, this results in a lower pressure at the opening and higher kinetic energy of the water stream. As a result, the velocity of the water squirted from the hose increases, allowing it to travel a greater distance.
