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

apparatus. Reynolds number for the tests at ∆P=5psi is 5.3913×10-5 and for ∆P= 30 psi is 1.1147×10-4. Laminar flow conditions exist so that Darcy’s equation is applicable. 2.0 Introduction When fluid flows through a medium‚ the flow is affected by the property of the medium that allows the flow of the fluid through it. The property of the medium is called permeability. Permeability

Mechanical devices are usually used to supply energy or driving force in order to make a fluid flow from one point to another .There are different kinds of mechanical devices used to transport fluids‚ namely‚ pumps‚ fans‚ blowers and compressors. Though liquids particularly can be transported by operators carrying buckets‚ the usual mode of transport of fluids is through pipelines with pumps‚ compressors‚ fans and blowers. Generally‚ the word “pump” designates a machine or device for moving an incompressible

Welding Process and Final Weld Shape A computer simulation accurately predicts weld pool fluid flow convection and final weld shape BY M. H. CHO‚ Y. C. LIM‚ AND D. F. FARSON ABSTRACT. The pulsed gas metal arc welding (GMAW-P) process was modeled numerically using a code based on the volume of fluid (VOF) technique‚ chosen primarily for its ability to accurately calculate the shape and motion of free fluid surfaces‚ which is needed for subsequent study of welding phenomena such as bead hump

Introduction: In any pipe system there is going to be a loss of energy due to the effect of viscosity from a fluid acting upon the surface of the pipe‚ this is called Friction Loss. This type of lost depends on the shear stress due to the walls of the pipe and the fluid. It also depends in weather the fluid is laminar or turbulent. A major difference between these two flows is that due to a viscous layer created in turbulent flow the roughness of the pipe can be taken in account while in laminar

TECQUIPMENT H10 FLOW-MEASURING APPARATUS 1.0 INTRODUCTION The Flow-Measuring Apparatus is designed to accustom students to typical methods of measuring the discharge of an essentially incompressible fluid‚ whilst at the same time giving applications of the Steady-Flow Energy Equation (Bernoulli’s Equation). The discharge is determined using a venturi meter‚ an orifice plate meter and a rotameter. Head losses associated with each meter are determined and compared as well as those arising in a

Figure 2 Ideal Power versus Head Pressure (H) · Sample Calculations · Raw Data Discussion of Experiment A centrifugal pump contains an impeller or set of vanes encased in housing. Energy is added to the fluid in the form of velocity and pressure as a result of the impeller turning. An engineer must determine the range of flow rates required when using a centrifugal pump. The centrifugal pump chosen for an application must have a head versus flow rate

Biology Chapter 29 “Do You Understand” Questions Chapter 29.1: 1) The roles of the blood plasma and the interstitial fluid in serving the needs of the body are to exchange materials and nutrients with the cells it surrounds. These two extracellular fluids interrelate because the plasma is 20% of all extracellular fluid and the interstitial fluid is the remaining 80%. 2) A) Epithelial tissues are sheets of densely packed‚ interconnected epithelial cells that cover inner and outer
