Water flows along a horizontal pipe of cross-sectional area 30cm2. The speed of the water is 4m/s but this rises to 75m/s in a constriction in the pipe. What is the area of this narrow part of the tube? | Fluid Dynamic
Cross-section area at one end (A1) = 30cm2
Cross-section area at another end (A2) = ?
Velocity at one end (v1) = 4m
