Question

A manometer connected to a closed tap reads 3.5 x 10'N/m², when the valve is opened, the reading of manometer falls to 3 x 105 N/m”, then velocity of flow of water is a) 100 m/s b) 10 m/s c) 1 m/s d) 10/10 m/s​

Answer 1

Answer:

A manometer connected to a closed tap reads 3.5xx10^(5)N//m^(2). When the value is opened, the reading of manometer fall is 3.0xx10^(5)N//m^(2), then velocity of flow of water is. ⇒v2=2×0.5×105103⇒v=100⇒10m/s.
