QUESTION 2 Use the continuity, momentum and Bernoulli's equations to calculate the head loss coefficient for a sudden expansion. Assume that the frictional pressure drop can be neglected in this entire sudden expansion, that the fluid has a constant density, and that the pressure is uniform across section 2.

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...

Pipes transporting domestic waste can get clogged due to solid particles slowly accumulating on the inner walls of the pipe. The objective of this question is to build a simple model to estimate how clogging affects the magnitude of the primary losses in such a pipe. We consider a cylindrical pipe of length L, initial diameter Do and initial roughness Eo. Waste, assumed to be a Newtonian liquid of density ρ and dynamic viscosity μ, circulates in this pipe at...
