Summary
The name of the equipment used for this experiment is TecQuipment Reynolds Number and Transitional Flow Apparatus, H215/215A TecQuiment Hydraulic Bench, H1. This equipment is used to see the pattern of the water flow rate. This equipment can help us to find pattern of flow rate and also can help us to calculate the flow rate of the water. It is important to study how to use the Reynolds number to calculate the flow pattern and also the Reynolds numbers can be used to calculate other properties such as density, velocity, diameter and viscosity. We must understand that Reynolds number is a ratio of inertia to viscous effect of a flow. The experiment was conducted in UNITEN lab with my lab mates and was supervised by my lab instructor Mr. Ibrahim. The procedure and rules which has been taught by Mr. Ibrahim were strictly followed. We handle the equipment with care to avoid any damage. Before opening the pipe flow we checked all the safety precaution and the experiment is done one by one by my group members and me.
Objective
To investigate the relationship of flow condition and fluid velocity.

Data, Observations and Results Table 1
Sample calculation
Flow rate, Q = volume(mᵌ)time(s)
= 0.001259
=0.00000385 mᵌ/s

The area is A=πd²4
= 3.14159×(0.012)²4
=1.13×10^ (-4) m²

(B) Graph 1: kinematics viscosity graph
With the above graph the kinematics viscosity is = 0.9×10^ (-6) m²/s

The equation use to find Re number is from equation 5 which is:

Re=udV…………. (5)
=0.135(0.012)0.9×10^ (-6)
=1797.34(transition flow)

is observed, there are laminar, transition and turbulent flow. The volume of water is fixed for certain values and the times are recorded. Based on the results, the ranges are calculated for laminar and turbulence flow. It was proved that the Reynolds number is dimensionless by using the units only and using the appropriate formula.

Milton Reynolds (1892–1976), an American entrepreneur, was born Milton Reinsberg in Albert Lea, Minnesota. He is most famously known for the manufacture and introduction of the first ballpoint pen to be sold in the U.S. market in October 1945. He was also inventor of the “talking sign” promotional placard for retail stores, sponsor and crewman on the twin-engine propeller flight that broke Howard Hughes’ round-the-world record,[1] and among the first investors in Syntex, which pioneered the combined…

ABSTRACT Reynolds number can be defined as a number of varieties of situations where a fluid is in relative with motion to a surface. This experiment is to observe the behavior of the flow of fluid either it is laminar or turbulent by calculating it's Reynolds number and the characteristic of the flow. Other than that, the range for laminar and turbulent flow can be calculated and the theory that Reynolds number is dimensionless can be proven. The pump is opened to let the water flow. The dye…

dimensionless. 2.0 INTRODUCTION In this Reynolds-Osborne Demonstration experiment, the characteristics of laminar, transitional and turbulent flow is to be studied by deriving their Reynolds (Re) number. The flow being studied is defined as an internal flow constrained by an overarching surface where the Re number can be easily determined. The apparatus for the demonstration consist of a circulating water system, elevated water input…

revealing a distinguishable form, so does David Reynolds sculpt the transformation of America to those unfamiliar with the events leading up to World War II. He whittles away an apparent formless generic history and makes sense of the events by exhuming certain concepts. For instance how President Franklin D. Roosevelt helped change the perspective of a reluctant United States to enter a war until the attack on Pearl Harbor. In addition, Reynolds examines the policies between 1938-1941 that were…
