Friction loss is the loss of pressure that occurs in hose flow because of the fluid's friction near the surface of the hose.
The amount of friction loss increases the more gallons per minute you push through a fixed-size hose. To reduce friction loss, you need to increase your hose diameter to accommodate the desired flow rate and distance your water will be traveling to reach your sprinkler.
