Water flows through a pipe AB of diameter d1=50mm, which is in series with a pipe BC of diameter d2=75mm in which mean velocity v2=2m/s. At C the pipe forks and one branch CD is of diameter d3, such that the means velocity v3 is 1.5m/s. The other branch CE is of diameter d4=30mm and conditions are such that the discharge Q2 from BC divides so that Q4=1/2 Q3. Calculate the values of Q1, v1,Q2,Q3,d3,Q4 and v4
