Extracted text: A fluid of constant density flows at the rate of 15 li/sec along a pipe AB of 100-mm-diameter. This pipe branches at B into two pipes BC and BD each of 25 mm diameter and a third pipe BE of 50 mm diameter. The flow rates are such that the flow through BC is three times the flow rate through BE and the velocity through BD is 4 m/sec. Find the flow rates (m^3/s) in the three branches (a) BC, (b) BD and (c) BE. ,
