, 1-PIPE FLOWS: Introduction
In this section we’ll study the effects of viscosity on incompressible, flows i.e.
we’ll deal with non ideal or viscous fluids
Such flows are of particular importance to engineers. Flow in a circular
pipe is undoubtedly the most common as it is encountered in the veins and
arteries in a body, in a city’s water system, in a farmer’s irrigation system…
The Reynolds number was observed to be a ratio of the inertial force to the
viscous force. Hence, when this ratio becomes large, it is expected that the
inertial forces may dominate the viscous forces. We need to focus on the
importance of Re in the definition of the flow regime
We will relate the definition and calculation of the head losses to the flow
regime
We’ll learn to solve simple hydraulic systems
