Question

A horizontal pipeline carrying gasoline has a cross sectional diameter of 5 mm. If the viscosity and density of the gasoline are 6 10^-3 Poise and 720 kg/m^3 respectively, the velocity after which the flow becomes turbulent is

Accepted Answer

Correct answer: D. (c) As Diameter of pipe (d )=5 mm=5 10^-3 m Density of gasoline ( )=720 kg/m^3 Viscocity of gas0oline ( )=6 10^-3 Poise The flow of water becomes turbulent after critical velocity. Critical velocity, v_c= ρd= 6 10^-3720 5 10^-3 = 6 10^-33600 10^-3=1.66 10^-3 m/s
