Pressure drop varies linearly with velocity for laminar flow in
a pipe flow. At a large Reynold’s number encountered in turbulent
flow, how do you anticipate pressure drop to vary with flow
velocity? Just need a general direction help.

why does laminar flow have less pressure drop than turbulent flow
Fluid Mechanics #1 Laminar Flow in Pipes The axial velocity in a pipe of radius R is given by, . Find the value of r (as a fraction of R) that maximizes u(r). How does this value of velocity compare with Vc? Compute the wall shear stress, du or Perform a control volume analysis on a pipe section of length e. Relate the pressure drop across the pipe section to the shear stress. Substitute the relation above for tw to...
Question The pressure drop Ap, along a straight pipe of diameter D has been experimentally studied, and it is observed that for laminar flow of a given fluid and pipe, the pressure drop varies directly with the distance I, between pressure taps. Assume that Ap is a function of D and I, the velocity V, and the fluid viscosity H. Use dimensional analysis to deduce how pressure drop varies with pipe diameter. [Hint: Use the method of repeating variables, Ap...
Problem 2 Find the velocity profile for steady, fully-developed, laminar flow in a circular pipe. Integrate this velocity profile to find the mass flowrate through a pipe of length L for a given pressure drop Ap.
For pressure driven flow of a liquid in a circular pipe, give the correct relationship between maximum axial velocity and average axial velocity for both laminar and turbulent flow conditions.

Considera steady, incompressible laminar flow of a Newtonian fluid in a pipe ignoring the effects of gravity. When a constant pressure gradient is applied in the x-direction, demonstrate that the maximum velocity of the fluid is given by 2 times of its average velocity.

Water flowing through a pipe assumes a laminar-flow velocity profile at some section is parabolic: u(0) -4J Figure 2 where u(r) is the velocity at any position r, ß is a constant,-11s the viscosity of water, and r is the radial distance from the pipe centerline. (a) Develop an equation for u(r) assuming a parabolic velocity profile and using the known velocities at the walls u(ro)-0 and the center u(0) (Just use symbols). (b) Develop an equation for shear...
