Consider fully developed pressure-driven flow in a cylindrical tube of radius, R , and length, L = 10 mm, with flow generated by an applied pressure gradient, Δ p . Tests are performed with room temperature water for various values of R , with a fixed flow rate of Q =10 μ L/min. The hydraulic resistance is defined as R hyd = Δ p / Q (by analogy with the electrical resistance R elec = Δ V / I , where Δ V is the electrical potential drop and l is the electric current). Calculate the required pressure gradient and hydraulic resistance for the range of tube radii listed in the table. Based on the results, is it appropriate to use a pressure gradient to pump fluids in microchannels, or should some other driving mechanism be used?

Oil flows at 55.9L/s in a pipe of 160mm diameter and 50m length. SG of oil is 0.9 and viscosity is 0.04 Pa-sec. If head loss is 5.22m, determine:
a. Mean Velocity of flow (m/s)
b. Type of flow
c. Friction Factor
d. Velocity at the centerline of pipe (m/s)
e. The shear stress at the wall of the pipe (Pa)
On a single plot, show curves that show the relationship between the pressure generated by thepump as a function of flow rate of water at 20 °C through the three branches of the piping systemshown below (delta P on the y axis and flow rate on the x axis; therange of the pressure should be 0 to ~1 MPa).
Pipe inner diameter: 0.03 mPipe material: copperTypical mass flow rate of interest: 0.5 kg/sIgnore minor losses of tee's at points A and B and any features of branch 3Consider minor losses of two 90° elbows in branch 2
A pipe is often used to assess the
flow rate of water in the center of a
pipe with an internal diameter of
102.3 mm at 20°C (density =
998.3 kg/m3, viscosity = 1.005
CP). The pitot tube coefficient is
0.98, and the manometer reading
is 10 mm of mercury at 20°C
(density = 13,545. 85 kg/m3).
Compute the velocity at the
center and the water's volumetric
flow rate
