Firefighters are holding a nozzle at the end of a hose while trying to extinguish a fire. If the nozzle exit diameter is 13.2 cm and the water flow rate is 11.54 m3 determine the magnitude of the horizontal resistance force required of the firefighters to hold min the nozzle, in kN. Assume the flow is uniform exiting from the nozzle. Give your answer to 2 decimal places. Take the density of water to be 1000- kg m3.

Forms of Energy

Energy is described as the capability to accomplish a task, like the ability to push a block by applying force on it. It is a quantitative property that is used to accomplish work on an object.
