Water supply in a house relies on an underground open reservoir and a pump. The distance betweer
the pump and the farthest tap is 10 m in the vertical direction plus 5 m in the horizontal direction. The inne
diameter of all the pipes and faucets is 20 mm. Find the gauge pressure introduced by the pump in order t
ensure a flow rate of 30 L/min. Suggestion: Indicate separately the different contributions to the pressur
including that due to viscosity. Data: coefficient of viscosity of water 1.1-10-3 Pa-s.
