Question

Glycerin at 40°C with ρ=1252 kg/m3 and μ=0.27 kg/m·s is flowing through a 4-cm-diameter horizontal smooth pipe with an average velocity of 3.5 m/s. Determine the pressure drop in kPa per 10 m of the pipe.

Answer 1

Answer:

0.048 L/s.

Explanation:

Glycerin at 40°C with ρ = 1252 kg/m3 and µ = 0.27 kg/m-s is flowing through a 2-cm-diameter, 25-m- long pipe that discharges into the atmosphere at 100 kPa. The flow rate through the pipe is 0.048 L/s.
