What is the pressure drop per unit length along the tube

Reference no: EM13534515

It is known that the velocity distribution for steady, laminar flowin circular tubes (either horizontal od vertical) isparabolic. Consider a 10 -mm- diameter horizontal tubethrough with ethyl alcohol is flowing with a steady mean velocity.15 m/s.

a. Would you expect the velocity distribution to be parabolic inthis case? Explain.

b. What is the pressure drop per unit length along the tube?

Hint: The flow will be laminar if the Reynolds number Re=ρvd/μ, remains below about 2100.

V= Δρh^2/12μl
