D ¶ L The water in a large tank exits through a horizontal circular pipe of diameter D=0.01m and length L=62m. The centre of the exit of the pipe is h=1.4m below the water surface. We can assume that the flow entrance to the pipe is smooth so that there are no minor losses. The flow in the pipe is laminar, the friction factor can be assumed constant and can be found from fp = 64/Rep where the Reynolds number is based on the pipe diameter and mean flow speed in the pipe. Taking frictional losses into account, solve the resulting quadratic equation to calculate the speed of the flow out of the pipe. Give your answer in m/s to 2 decimal places. Use: kinematic viscosity given by v=0.00000114 m²/s density of water given by 1000 kg/m³ acceleration due to gravity of 9.81 m/s²
