Question

(Free Response) 16: Water (density - 1000 kg/m) flows at a rate of 0.32 m''s into a horizontal pipe of diameter 40 cm. The 40-cm-diameter pipe is 5.0 m above a 60 cm diameter honzontal pipe that is connected to it. The water pressure in the wider pipe is 1 atm Calculate (A) the water speed in the thinner pipe (B) the water speed in the wider pipe 5.0 m (C) the water pressure in the thinner pipe.
