Question
Water at 80◦C flows steadily from a tank shown below at a volume flow rate of 475 L/min to a pump through
a 62.7-mm diameter steel pipe. The roughness element size is 46 μm. The kinematic viscosity of water is
ν = μ/ρ = 3.60 × 10−7 m2/s. The tank is open to the air through a hole shown in the figure. If needed, use
the table and the Moody chart on the next page.
