Problem 3. a. Gasoline GHS label usually come with these symbols below. What do they mean? (5) Gasoline DANGER b. NFPA diamond for gasoline is shown below. What do the color and numbers mean? (5) NFPA Diamond for E-100, E-95. C 85, and Gasoline O c. Let's calculate how safe it is in the gas station when you are filling the gas in the car. A Subaru Outback has a gasoline tank of 14 gal volume and it usually takes 3 min to fill the gas. Estimate the concentration of gasoline vapor (in ppm) at the gas station? Please assume molecular weight of gasoline is 94 lbm/lb-mole, vapor pressure of gasoline is 4.6 psi at 77 F, and ventilation at the gas station is 3000 ft/min. Assume, specific gravity of gasoline is 0.713. Assume, k = 0.1. Ideal gas constant, Rg = 0.7302 ft³-atm/lb-mole-R. Conversion of Rankine, R = 460+ F, 1 gal = 0.1337 ft³, 1ft of water = 62.43 lbm of water (10)
