Water from a pipe is coming at a rate of 100 litres 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 = 1000 kg/m³, coefficient of viscosity of water = 1 mPa s)(A) 10³(B) 10⁶(C) 10²(D) 10⁴

Answer»

Answer:

OPTION (D) 10⁴

Explanation:

Reynolds number = p v d / n

Volume of FLOW RATE = v * π r^2

On putting the numbers we GET, approx. 2 * 10⁴

HOPE THAT IT WAS HELPFUL!!!!

MARK IT THE BRAINLIEST IF IT REALLY WAS!!!!
