3. The specific gravity of gasoline is approximately 0.70 . (a) Determine the mass ( kg ) of 50 Litres of gasoline. (Spts) (b) The mass fow rate of gasoline exiting finery tank is 1150kg/min. Estimate the (Spts) (d) Gasoline and Kerosene (specific gravity 0.82 ) are blended to obtain a mixture with a specific gravity of 0.78 . Calculate the volumetric ratio (volume of gasoline/volume of kerosene) of the two compounds in the mixture, assuming Vblend=Vgasoline+Vkerosene. (5pts)
