Units are on the scene of a big box store fire and command requested Engine 51 to return to the hydrant and pump the 5" hose line (LDH). The LDH is lying horizontally and under hydrant pressure in a steady flow, the sum of all forms of mechanical energy in the water along the hose is the same at all points on the hose. As the pump pressure is increased the speed of the water occurs proportionately with an increase in kinetic energy. This is an example of __________.

-force and pressure

-turbulent flow

-laminar flow

-viscosity
