A light oil is flowing through a commercial steel pipe of diameter D1. The head available to produce flow is independent of the flow rate. It is decided to utilise this head to increase the oil flow rate fourfold by installing a second pipe in parallel with the first pipe and of the same length. What should the diameter of the second pipe be, if: (i) flow in each of the two pipes is highly turbulent and the same roughness...

Water flows at speed of 6 m/s through a horizontal pipe of
diameter 3.5 cm. The gauge pressure P1 of the water in the pipe is
1.7 atm. A short segment of the pipe is constricted to a smaller
diameter of 2.4 cm .
What is the gauge pressure of the water flowing through the
constricted segment? Atmospheric pressure is 1.013 × 10^5 Pa. The
density of water is 1000 kg/m^3 . The viscosity of water is
negligible. Answer in...
