Question

the water level. If the rate of flow from the leak is equal 16.0 m below 2.50 X 10-3 m3/min, determine (a) the speed the water leaves the hole and (b) the diameter of the hole. to at which A village maintains a large tank with an open top, contain- ing water for emergencies. The water can drain from the tank through a hose of diame ter 6.60 cm. The hose ends with a nozzle of diameter 2.20 cm. A rubber stopper is in- serted into the nozzle. The water level in the tank is kept 7.50 m above the nozzle. (a) Calculate the friction force exerted by the nozzle is removed. What mass of water flows from the nozzle in 2.00 h? (c) Calculate the gauge pressure of the flowing water in the hose just behind the nozzle. T on the stopper. (b) The stopper NOTAS COMENTARIOS Ps Lr
