Students are playing around with a water hose. When they point it straight up, the water jet just reaches one of the windows of an office, \(10 \mathrm{~m}\) above. If the hose diameter is \(1 \mathrm{~cm}\), estimate the water flow rate \((\mathrm{L} / \mathrm{min})\). A student places his hand just above the hose to make the jet spray sideways axisymmetrically. Estimate the maximum pressure, and the total force that he feels. The next day the students again are playing around, and this time aim at another window, \(15 \mathrm{~m}\) above. Find the flow rate (L/min) and the total force and maximum pressure when the window pane blocks the flow.
