A venturi meter is used to measure flow velocity. Given the manometer reading at A is 100 kPa, D = 10 cm, d = 5 cm, VA = 2 m/s, and specific weight of water is 9800 N/m3, what is the manometer reading at B? Note that flow rate (Q) is constant and Q = VA, where A is the area through which the flow is passing.
