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=0,00à009905m²/s so the fluid used by Martinuzzi is air but the viscosity of air is 0,00001511m²/s so iam confused
please help me if you are used this paper
thank you
