Question: A 50 mm diameter pipe is used to convey air at 4C (density 1.12 kg/m' and dynamic viscosity = 1.815 x 10-5 N s/m2)

A 50 mm diameter pipe is used to convey air at 4C

A 50 mm diameter pipe is used to convey air at 4C (density 1.12 kg/m' and dynamic viscosity = 1.815 x 10-5 N s/m2) at a mean velocity of 20 m/s. Calculate the discharge of water at 20C for dynamic similarity, and obtain the ratio of the pressure drop per unit length in the two cases.
