2. The mixture of fluid HC contains 10%n-heptane, 40%n-octane, and 50%i pentane by weight. The specific gravity (SG60F60F) of the pure components are n-heptane =0.685,n-octane =0.705, and i-pentane =0.622 (use H2O=62.4lbm/ft3 ) a. What is the SG60F60F of 93lbm of this mixture? b. How many US gallons will be accepted by 130lbmm of this mixture? 3. Calculate the density of mercury in lbm/ft3 from a tabulated specific gravity, and calculate the volume in ft3 occupied by 215kg of mercury. SAMPLE PROBLEMS ON SPECIFIC GRAVITY 4. If dibromopentane (DBP) has a specific gravity of 1.57. what is the density in (a) g/cm3; (b) 1lom/ft3; and (c) kg/m3? 5. Five thousand barrel (bbl) of 28API gas oil are blended with 20,000 bbl of 15 oAPI fuel oil. What is the density of the mixture in lb/gal and lb/ftt3. Assume that the volumes are additive, 1bbl=42gal, Density of water at 60F is 0.999g/cm3
