B A common problem in food adulteration is the dilution of olive oil with cheaper oils. The viscosities and densities for some common oils are listed in the table below. n mPa*s p g/cm3 To test the olive oil, a viscometer is made with a 20 olive oil corn oil peanut oil 84 30 40 1column of 92 92 column of liquid above a capillary tube through which the oil flows and is collected. The capillary tube is 6cm long and has a radius of 0.12cm. The oil is allowed to flow for Soy bean oil 8093 60 seconds and the volume of oil which has flowed out is measured. a) Derive an expression for the ratio p/n in terms of the dimensions the volume delivered and any constants you need. Mass and pressure should not the result.[6 points] b) Samples of two Slippery Guys Pressed Foreign Sirs of the viscometer, the time be present in brands of olive oil are analyzed using the viscometer with the results below. 24.98 cm 18.48 cm 25.03 cm 18.47 cm 25.02 cm 18.52 cm s either of them olive oil? Can you propose a possible identity of either of them? Support your answers with appropriate calculations. [14 points] c) A 1 cm diameter glass sphere (ρ=2.6 g/cm3) is dropped in a tall container of soy bean oil. Calculate the terminal velocity of the sphere and check the Reynolds number to make sure you use the proper formula. [8 points]
