Watering or Irrigatng its the same thing!

Believe it or not when watering through a hose or a pipe there is some quite complex physics going on inside the hose or pipe. If you know about this you can very simply increase the efficiency of your watering operation. The faster the water moves through a pipe, the greater the friction between the pipe and the water. This produces a layer of drag,  which has the effect of reducing the inside diameter of the pipe and this in turn restricts the amount of water that can flow down the pipe. OK the physics lesson has finished.
