First of all, the targets of the experiment are to take notice of the characteristics of the flow and to compute the Reynold's quantity. Using the Solteq Osbourne Reynold's Demonstration (model FM 11) in this try things out, with different of water volume flowrate, the characteristics of the stream could be established. The rock inside the stilling tank in order to calm the inflow normal water so that there will not end up being any disturbance interfere with the experiment. The water inlet and outlet valve and dye injector useful to generate the necessary flow. A dye treatment system is attached to top of the header tank in order that the pattern in the flow can be visualized. The characteristic with the flow can be observed, you will discover laminar, changeover and violent flow. The volume of drinking water is set for certain ideals and the occasions are documented. Based on the results, the ranges happen to be calculated for laminar and turbulence stream. It was proven that the Reynolds number is dimensionless utilizing the units just and making use of the appropriate method.

1 ) 1 LAUNCH
Osborne Renolds is a Uk scientist and mathematician was the first to distinguish the difference among these two classification of flow by using a straightforward apparatus to determine the flow of fluid in pipe which may be laminar or turbulent. For small enough flowrates, the dye steak(a steakline) will remain as a well-defined line mainly because it flow along, with simply slight cloudy due to molecular diffusion in the dye in to water encircling. For the larger intermediate flowrate, the dye streak fluctuates in time and space, and intermittent explodes of abnormal behavior seem along the ability. However , intended for large enough flowrates, the color streak practically immediately turn into blurred and spreads throughout the entire water line an a arbitrary fashion. These types of three characteristics, denoted since laminar, transition and violent flow. (F. Young, 2012)
1 . 2 TARGET
One of the goal is to calculate Reynold's amount (R) by making use of the formula.
An additional objective should be to observed the laminar, transitional and thrashing flow. This flow can be easily noticed by applying the dye going through the flowing water. Velocity of dye flow has to be control by adjusting the valve.
Apart from that, to determine the lower and upper critical velocities at transitional flow. Rate of change flow is in fact in between alisar and turbulent flow, hence the critical velocities of upper and lower must be determine. This can be conveniently determine simply by controlling the control device of coloring flowing to through the going water.
1 ) 3 Theory
The Osborne Reynold's exhibition apparatus is equipped with visualization conduit to observe the flow condition. The rock inside the stilling reservoir are to calm the influx water in order that there will certainly not be virtually any turbulence to interfere with the experiment. This particular inlet and outlet device and dye injector are used to generate the necessary flow. (Arif, 2010) Reynold number formulation: R=ULv
R sama dengan Reynold amount
U = fluid speed (m/s)
M = feature of duration or size (m)
V = kinematic viscosity (m2/s)
Reynold amount, R is independent of pressure
Water pipe Flow Condition:
