At what flow rate might turbulence begin to develop in a water main with a 0.200 m diameter? Use a value of Pa⋅s for the viscosity of water and assume that a Reynolds number of corresponds to the onset of turbulence.
The density of an unknown fluid is 0.78 g/mL. A 2-millimeter-diameter brass ballbearing takes 2.8 s to fall 25 cm through the fluid. What is the fluid’s viscosity?
The pressure drop in a flow of oil in a smooth and straight pipe of diameter 5.00 cm is kPa/m. Find the oil’s flow rate. Use a value of 0.90 for the specific gravity of oil and use a value of 0.10 kg/m⋅s for the oil’s viscosity.
