Assignment Help Mechanical Engineering

A fluid (viscosity=10^-2 Ns/m2, density =800 kg/m3) flows with a mean velocity of 4 cm/s in a 10 cm smooth pipe.

a. What is the value of Reynolds number?

b. What is the magnitude of the maximum velocity in the pipe?

c. What is the magnitude of the friction factor?

d. What is the shear stress at the wall?

e. What is the shear stress at a radial distance of 25 mm from the center of the pipe?
