The Kapandu boys dormitory in the UPNG is going up in flames. Rachel, a former student of Physics, who is now a fire fighter, is part of the team who have rushed onto the scene to try to contain the blaze. As she holds the fire hose, she experiences a force exerted on her by the hose. Provided the diameter of the fire hose is 7.0 cm, and the water running through the hose flows at 420 L/min, how much force does she need to hold the nozzle, if its diameter is 0.75 cm?
