The specific gravity of gasoline is approximately 0.70. (a) estimate the mass (kg) of 50.0 liters of gasoline. (b) the mass flow rate of gasoline exiting a refinery tank is 1150 kg/min. estimate the volumetric flow rate in liters/s. (c) estimate the average mass flow rate lbm/min? ? delivered by a gasoline pump. (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,
