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.
Keeping your garden flowering or producing fruit takes a combination of things, but adequate water is one of the most important. Plush, green lawns need attention from water too. Once you’ve done a quality job of watering your plants thoroughly, the roots will extend deep into the soil and provide both stability and durability for your lawn.
