What is the expected impact of increased friction loss on the irrigation system?

Increased friction loss in an irrigation system leads to a decrease in the flow rate of the water being delivered. This occurs because as water flows through pipes, fittings, and other components, it encounters resistance due to friction. The more resistance there is, the more energy is required to maintain the flow of water. If the friction loss increases, less water can flow through the system effectively, which results in a reduced flow rate at the output points, such as emitters or sprinklers.

Understanding this concept is critical for irrigation design and management. When planning an irrigation system, it is essential to take into account the layout, length of pipes, and number of fittings to minimize friction loss and maintain adequate flow rates for efficient watering.
