Final answer:
Jet pumps are powered by a motorized pump that drives fluid under high pressure. Large pumps, akin to those on fire trucks, can convert substantial power to increase water pressure, and may also affect fluid velocity and height.
Step-by-step explanation:
Jet pumps, like those used to supply fuel into the collector lines, are powered by external sources which can include a motorized pump. This type of pump does the primary work in the system, driving fluid under high pressure through the lines. An example can be drawn from some fire trucks, which use a large pump capable of converting a substantial amount of power (around 50 horsepower) to increase the water's pressure significantly.
When considering an operation such as a pump used in engineering contexts, it may be necessary to comprehend how it can also directly increase the fluid's velocity and height, in addition to pressure. To accurately calculate the total power that the pump supplies, all three aspects (pressure, velocity, and height) need to be considered, just as one would evaluate the mechanical work done by the heart in a biological system.
