Examine the transition between the laminar and turbulent flows of water by sketching the stream of water that exits from a faucet (without an aerator) or hose (without a nozzle). You can control the velocity of the stream by adjusting the water valve.
(a) Make sketches of the flow for four different fluid speeds: two below and two above the laminar-turbulent transition point.
(b) Estimate the velocity of the water by determining the time Δt required to fi ll a container of known volume, such as a beverage container. By measuring the diameter of the stream with a ruler, calculate the average speed of the water from Equations (6.9) and (6.10).
(c) For each speed, calculate the Reynolds number.
(d) Indicate the value of Reynolds number where turbulence begins.
