Water flows through a 2 cm diameter pipe at 1.6 m/s. Calculate the Reynolds numberand find also the velocity required to give the same Reynolds number when the pipe istransporting air. For the water the kinematic viscosity was 1.31*10^-6 m^2/s and the density was 1000 kg/m^3. For air those quantities were 15.1 10-6 m^2/s and 1.19 kg/m^3.
