Using a spherical separation funnel to measure the viscosity of red wine.The radius of the bulb is 5 cm. The vertical tube length is 10 cm and its radius is 1mm. The measured efflux time is about 100 s. Consider the density of the wine similar about 1000 Kg/m3. Initially the whole bulb was filled up. Please calculate the viscosity of the red wine.
