Q5) The average velocity of the air flowing in a pipe with a roughness of ks=D0.0015 mm with a diameter of 4 mm at standard pressure and temperature is V=50ms1. Under these conditions, the flow is normally turbulent. However, laminar flow conditions can be provided if some necessary conditions are met (if the entrance to the tube is softened, there are no dust particles in the air, etc.). According to this; a) What is the pressure drop in the 0.1 m section of the pipe? b) Repeat the same question for the condition that the flow is turbulent. (pair=1.23 N.s?m²; uair=1. 79 x 10-5 N.s.m2)

a diameter of 4 mm at standard pressure and temperature is V=50ms-1. Under these
conditions, the flow is normally turbulent. However, laminar flow conditions can be provided
if some necessary conditions are met (if the entrance to the tube is softened, there are no

a) What is the pressure drop in the 0.1 m section of the pipe?
b) Repeat the same question for the condition that the flow is turbulent.
