r a c t The three-dimensional flow field and the flow pathlines within a Tesla disc turbine have been investigated analytically and computationally. The description of the flow field includes the three-dimensional variation of the radial velocity‚ tangential velocity and pressure of the fluid in the flow passages within the rotating discs. A detailed comparison between the results obtained from the analytical theory and computational fluid dynamic (CFD) solutions of Navier–Stokes equations is presented

Picket Fence to travel the 5.0 cm. 2. If an object is moving with a constant acceleration‚ what is the shape of its velocity vs time graph? Answer: If an object is moving at a constant acceleration then the shape of the corresponding velocity vs time graph will look like a linear line going up diagonally on the graph. 3. Does the initial Velocity of an object have anything to do with its acceleration? For example‚ compared to dropping an object‚ if you throw it downward

Loadshedding Of Electricity! There are number of problems which exist in Pakistan‚among these problem Load sheeding is the one major problem of Pakistan .There are several reasons of Load shedding.The first main reason of load shedding is energy crisis‚these crisis are due to small number of dams or may be due to miss use of electricity or may be some other reasons also effect‚a huge number of pesrsons used electricity without paying its bill so it also cause load shedding in Pakistan.In presence

Projectiles Practical Report 1. Introduction Velocity is a vector measurement of the rate and direction of motion or‚ in other terms‚ the rate and direction of the change in the position of an object. [1] Velocity can be found many ways through various suvat Equations and their rearranged forms. For example v2=u2+2as in which the square of the final velocity can be found if you know the objects initial velocity‚ the acceleration and the distance travelled. Using such formulae makes it possible

Introduction The purpose of this section is to introduce the concepts of displacement‚ velocity‚ and acceleration. For the sake of simplicity‚ we shall restrict our attention to 1-dimensional motion. Displacement Consider a body moving in 1 dimension: e.g.‚ a train traveling down a straight railroad track‚ or a truck driving down an interstate in Kansas. Suppose that we have a team of observers who continually report the location of this body to us as time progresses. To be more exact‚ our observers

between sparks‚ we can calculate a set of average velocities for the plummet using the definition: v = Dx Dt It can be shown that the average velocity during any time interval is equal to the instantaneous velocity at the midpoint in time of the interval‚ provided that the acceleration is constant during the time interval. The set of average velocities described above may then be treated as a set of instantaneous velocities. Once velocities are known at definite times‚ we can find the average

Use kinematic graphs to catalog objects that exhibit similar motion. PRELIMINARY QUESTIONS: Finding the average velocity Do any of the four objects listed above move in similar ways? If so‚ which ones? What do they have in common? Yes‚ the ball and the jump both move in similar ways. Due to the acceleration to be constant for both. The pendulum and the spring move
