of flow of liquids. It aims to classify if the flow of is either laminar or turbulent. Reynolds number is a dimensionless quantity that gives the ratio of kinetic or inertial forces to viscous force in the fluid condition. The bigger the Reynolds number the more orderly is the flow of the fluid molecules. The experiment uses a small stream entering dye with flowing water to observe its behavior through the glass pipe. The observation of the dye behavior will be supported by the Reynolds number calculation

In the average person water constitutes 60% to the total body weight.: 42L in a 70kg individual. 40% is intracellelular fluid‚ while remaining 20% is extracellular. The extracellular fluid can be divided into plasma (from intravascular compartment) and interstitial fluid intracellular fluid (28 L‚ about 35% of lean

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

Bernoulli’s theorem i Bernoulli’s theorem‚ in fluid dynamics‚ relation among the pressure‚ velocity‚ and elevation in a moving fluid (liquid or gas)‚ the compressibility and viscosity (internal friction) of which are negligible and the flow of which is steady‚ or laminar. First derived (1738) by the Swiss mathematicianDaniel Bernoulli‚ the theorem states‚ in effect‚ that the total mechanical energy of the flowing fluid‚ comprising the energy associated with fluid pressure‚ the gravitational potential energy of

5.2 Principle of Operation of N-Channel JFET: These are two prerequisites while considering the principle of operation of JFET. Gates are always reverse biased and therefore Gate current IG is practically zero. Source and Drain terminal should be joined together through a voltage source called VDS‚ drain to source voltage. In an N-channel JFET‚ source terminal is connected to the negative end of the drain to source supply voltage to send the lectron from source to drain and similarly for an P-channel

1.0 ABSTRACT The objectives of handling this experiment are to study the characteristics of laminar‚ turbulent and transition flows by calculating the Reynold’s number of each flow and by observing the behavior of the flow itself. Besides that‚ this experiment is in conduct in order to determine the range for laminar and turbulent flow as well as to prove that Reynold’s number is dimensionless by calculating by using the formula. The experiment was started with laminar flow. In order to obtain the
