brayan is on a distinguished road
i am reeding the paper of Martunizzi "
Martinuzzi, R. and Tropea, C., 1993, The flow around surface-mounted,
prismatic obstacles placed in a fully developed channel flow"

he used the Renolds number Re(h)=100000 the bulk velocity UB=19.81m/s h of channel =0,05m so when i calculated the kinematic viscosity=0,00009905m/s so the fluid used by Martinuzzi is air but the viscosity of air is 0,00001511m/s so iam confused
please help me if you are used this paper
thank you
