Answer 1

Explanation:

Well Losses: Well losses refer to the additional head loss that occurs as water flows through the well screen and into the pump. This can be due to several factors, including the resistance offered by the well screen, clogging, or other obstructions within the well.
Clogging: When a well screen becomes clogged, the resistance to water flow increases, leading to a higher head loss or well loss. This is typically observed as a decrease in the efficiency of the pump, as more energy is required to draw the same amount of water.
High Well Losses: A high value of well losses is a direct indicator that there is an obstruction or clogging in the well screen. This condition results in increased energy consumption by the pump and reduced overall efficiency.
