Water flows at 7 m/s in a pipe of radius 5 cm. A plate having an area
Question:
Water flows at 7 m/s in a pipe of radius 5 cm. A plate having an area equal to the cross-sectional area of the pipe is suddenly inserted to stop the flow. Find the force exerted on the plate. Take the speed of sound in water to be 1.4 km/s. (Hint: When the plate is inserted, a pressure wave propagates through the water at the speed of sound vs. The mass of water brought to a stop in time ∆t is the water in a length of tube equal to vs ∆t.)
Step by Step Answer:
We find m of water in l...View the full answer
