Consider the semi-trailer EMIRSAN 42000 LT Fuel tanker shown below. When the tank is fully empty, the mass of the entire vehicle is 30 metric tons (or tonnes). Find the following: A. The length (L), in meters of this cylindrical tank if its radius (r) is 1.7 m. B. The mass (M), in metric tons of the entire vehicle if the tank is full of Kerosene; the fuel density is 0.8 g/mL at 25C. The fuel has a uniform temperature of 25C. GANGEROUS CNRSAN CEMINSAN EMIRSAN EMIRSAN C. If an unknown fuel occupies 75% of the total tanker's capacity and the remaining 25% is kept empty, identify the fuel type if the gross mass of the vehicle is 56.775 metric tons.
