20°C water ==> density = ρ = 1000 kg/m³
r = d/2 = 0.0165 m
A = 0.000855 m²
Q = ΔV/Δt
Q = volumetric flow rate
ΔV = change in volume flowing through the area
Δt = time interval of volumetric flow
Also:
Q = v · A = vA cos θ
v = velocity field of the substance elements flowing
A = cross-sectional vector area/surface
θ = 0 ==> cos θ = 1
v = Q/A = Q/0.000855
r = d/2 = 0.0165 m
A = 0.000855 m²
