A steel projectile of 5 mm diameter (p, 7,705 kg/m) leaves the muzzle of a gun at a speed of 265 m/s and travel in the air briefly before entering a water pool at a speed of 160 m/s. Assuming the air density pa-1.07 kg/m3 and viscosity of air is a 1.8 105 kg/(ms), and water density Pw-990 kg/m and viscosity w 1.05 103 kg/(ms). Determine the Reynolds number of the projectile in the air and in the water and enter the higher Reynolds number of the two accurate to 4 significant figures.
