A boat has a propulsion system that consists of a pump that sucks water at the bow and presses it on the stern. All tubes are 5 cm in diameter and the outlet flow is 50 L/s.
Calculate the propulsion force at the moment of departure, that is, with the boat at rest. The pressure at the inlets and outlets is assumed to be practically atmospheric (water density = 1000 Kg /m3).
