Q10.Water from a pipe is coming at a rate of 100 liters per minute. If the radius of the pipe is 5 cm, the Reynolds number for the flow is of the order of: (density of water = 100 kg / m3, coefficient of viscosity of water = 1 mPa s ) (1) 102 (2) 104 (3) 103 (4) 106
What This Question Tests
This question involves calculating the Reynolds number for fluid flow in a pipe, requiring conversion of units and relating flow rate to average velocity.
Concepts Tested
Formulas Used
