At the end of the day, you and two of your colleagues are washing down an excavator with pressure washers. When water hits the excavator, it runs vertically down the sides. You have the "good" pressure washer that has a flow rate of 3 x 104 m³/s and emits a stream of water with a diameter of 5 mm. Your colleagues each have a wimpier model that has a flow rate of 1.5 x 104 m³/s and emits a stream of water with a diameter of 4 mm.
