friction factor for laminar & turbulent flow in a smooth pipe over a range of Reynolds’s number . 2. To obtain the following relationships : a. Head loss as a function of the velocity of flow . b. Friction factor as a function of Reynolds number . Theory : The friction resistance to the flow of fluid through a pipe results in a loss of pressure energy for a given fluid flowing a long a given pipe‚ experiments show that for laminar flow : Hl α V And for turbulent flow : Hl α Vn Where : Hl

“The Weimar Republic collapsed because of the economic problems faced by Germany” The Weimar republic‚ created almost by accident on the 9th of November 1918‚ lasted only fifteen years. The reasons for its collapse are many and varied and while the economic difficulties faced by the republic significantly contributed to its collapse‚ these difficulties would not have happened had it not been for other influencing factors. Essentially the collapse of the Weimar republic began with its creation

eddies in the flow which causes mixing between the high energy and low energy layers of fluid. This is called “turbulent flow” and under these conditions it is found that the relationship between shear stress and velocity gradient varies depending on many factors in addition to the viscosity of the fluid. Reynolds realized that laminar flow is the result of viscous forces and that turbulent flow is in some way related to inertia forces. He postulated that the nature of flow depended on the ratio of

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

ABSTRACT The aim of this experiment is to study the friction loss along a pipe. In this experiment‚ water and mercury have been used to demonstrate the law of resistance with different types of flow which are laminar and turbulent flow. The variation of head loss will be obtained and hence determined the Reynold numbers and friction factor. In the end of the experiment‚ the law of resistance which is the relationship between i and u will be determined and hence established the critical R and friction

At the age of eight‚ his grandfather was killed by Muhammad’s own uncle Abu Talib (Kikim). Muhammad had a very turbulent childhood characterized by living in various homes‚ which made him the person he became in his later years. During Muhammad’s adolescent years‚ there were no laws or order in Arabia. The Arab nation was divided into many different tribes; most people

The solver is using a full-scale time-marching 3D viscous model. Underlying equations‚ three dimensional Navier-Stokes equations in their conservation form‚ are being solved by using a Finite Volume method‚ where equations are integrated over the finite control volumes. Thereby‚ the solution domain is subdivided

Findings – The paper finds that first‚ it was proposed that more successful companies in turbulent environments would use radical‚ fast and disruptive strategies. Furthermore‚ strategy making should be a democratic‚ bottom-up process and should be organic‚ self-organising‚ adaptive and emergent. The results confirmed these propositions. Second

characteristic size‚ and v the fluid kinematic viscosity. When the Reynolds number is low‚ the current lines are stationary‚ and the flow is said laminar. In contrast‚ when the Reynolds number is higher‚ the streamlines become unsteady and the flow is said turbulent. To these two fundamentally different types of flow match different load losses. The aim of the experiment is to evaluate in a vast range of pipe flow‚ the pressure drop and find the value of the Reynolds number in the case of laminar and
