1. A pressure drop of 50 kPa due to fluid friction through 1-in wrought iron pipe ismeasured. The fluid flows at a rate of 0.04 kg/s. The fluid viscosity is 2 cP and itsdensity is 1000 kg/m3. Find the length of the pipe? 2. Liquid is flowing at a rate of 20 L/min in a 1.5-in diameter sanitary pipeline. The liquid has a density of 1030 Kg/m3 and a viscosity of 50 cP. Find the mean and maximum velocities and state whether the flow is laminar or turbulent?
