Problem
In an irrigation system, water is siphoned through a hose from a pond to a field located 2.3m lower than the pond surface. Internal friction in the hose removes 18% of the mechanical energy per unit mass between the pond surface and the outlet. Estimate the speed of the water as it exits the hose. State the value in ms−1 to two significant figures.
