A venturimeter,consisting of a converging portion followed by a throat of constant diameter and then gradually diverging portion,is used to detremine the flow of
the pipe.The diameter at section 1 is 6 in. and that of section 2 is 4 in.,Find the discharge through the pipe when p1-p2=3psi and oil of sp grvty 0.9 is flo
wing
Solution:
From the continuity equation Q=A1v1=A2v2
Therefore,v1=Q*16/pi , v2=Q*36/pi
And moreover Z1=Z2
Therefore discharge Q =
