A pressure washer or power washer is a machine commonly used to clean mildew and dirt off houses, driveways, sidewalks etc. It attaches to a common garden hose, pumps pressure of water up, and lets it flow through a small nozzle at the end of a wand. The force of the resulting water jet physically knocks the mildew off. Estimate the maximum force (lbs.) that a water jet from a powerwaher can make on a glass window. Assume the water jet flows from the nozzle at a velocity of 40 ft/s. Also assume the jet is round with a diameter of 0.25 in.
