Where does the greatest amount of pressure occur in a hose?

In a hose, the greatest amount of pressure occurs near the pump because this is where the water is being pushed into the hose at high velocity. The pump generates the force needed to move the water through the hose, creating pressure as the fluid is forced into the confined space.

As the water travels along the hose, friction between the water and the internal walls of the hose causes some pressure loss, reducing the pressure as it moves further away from the pump. Therefore, the pressure tapers off along the length of the hose, and while some pressure does build up near the nozzle, it is primarily the pressure created by the pump that sets the conditions at the point closest to it.

This understanding is crucial for effective management of water systems, such as in aquatic pest management, where knowing the dynamics of water pressure can influence the efficiency of application techniques.
