Dear student
 

Reynolds number is given by

R = ρvd/η

The volume of the water flowing out per second is

Q = v × πd2/4

v = 4Q/d2π

R = ρvd/η

R = 4ρQ/πdη

ρ = Density of water = 103 kg/m3

Q = 3 L / min = 3 × 10-3 / 60 = 5 × 10-5 m3/s

d = 2/√π × 10-2 m = 1.125 × 10-2 m

η = Viscosity = 10-3 Pa.s

So, R = (4 × 103 × 5 × 10-5)/(3.14 × 1.125 × 10-2 × 10-3)

R ≅ 5500
