The velocity field of a flow is given by v = 2x2ti [4y (t 1) 2x2t] j m s, where x and y are in meters and t is in seconds. for fluid particles on the x axis, determine the speed and direction of flow. first, determine the speed of flow. part 2 determine the direction of flow.
Solved A Velocity Field Is Given By V Xj Velocity Fields о Your solution’s ready to go! our expert help has broken down your problem into an easy to learn solution you can count on. question: the velocity field for a flow is given by v = u i v j w k ,, where u = 3x, v = −2y, w = 2z. find the streamline that will pass through the point (1, 1, 0) the velocity field for a flow is given by v = u i. The quantity v (x, y,z,t) is called the velocity vector field. it can be thought of at each instant in time as a collection of vectors, one for each point in space whose direction and magnitude describes the direction and magnitude of the velocity of the fluid at that point (figure 28.1). this description of the velocity vector field of the. For simplicity, let’s assume that v(x, y,z,t) = v. x (x,t)öi ; there is only a non zero x component of the velocity and the only non zero change is in the x direction. consider a fluid element of volume δv = δ xδ yδ z , then the fluid element will undergo a change in volume.

We can use q = a v ¯ q = a v ¯ to calculate the speed of flow in the aorta and then use the general form of the equation of continuity to calculate the number of capillaries as all of the other variables are known. solution for (a) the flow rate is given by q = a v ¯ q = a v ¯ or v ¯ = q πr 2 v ¯ = q πr 2 for a cylindrical vessel. Primary dependent variable is fluid velocity vector v = v ( r ); where r is the position vector if v is known then pressure and forces can be determined using techniques to be discussed in subsequent chapters. consideration of the velocity field alone is referred to as flow field kinematics in distinction from flow field.
