please do problem 3. data table is on the 2nd photo.

3. (12 points) The idea of the Siemens Power-to-X program is to use electricity to create carbon-neutral fuels. Two such fuels are hydrogen and methanol. Water electrolysis powered by renewable electricity will supply the hydrogen for these fuels, and biogenic CO2 will supply the carbon in methanol. This problem considers only the electrolyzer electricity required to make hydrogen for these fuels. The electrolyzer operates with a typical voltage of 1.8V, and production of one mole of H2 requires 1.93105 Coulombs (two times Faraday's constant). With this information (and the table in problem 1), determine the following: (a) The ratio of electrolyzer energy to fuel heating value for H2 and for CH3OH. (b) The electrolyzer energy, in units of GJe, to produce the hydrogen in H2 used for the Boeing 737-800 airplane in problem 1. (c) As in (b) except for the hydrogen in methanol (CH3OH). (d) The electrolyzer power, in units of MWe, for hydrogen production in H2 that matches the power of fuel consumption at cruise altitude ( 850 gal kerosene/hr). (e) As in (d) except for the hydrogen in methanol. 1. (12 points) In transportation, fuel volume and weight are important aspects in design. This problem considers a Boeing airplane, but the ideas also apply to other forms of transportation. The Boeing 737-800 has a fuel capacity of 6,875 gallons of jet-A fuel, which can be considered as kerosene. The fuel tanks are located in the wings. Without fuel, the jet weighs 41mt. The volume of its fuselage is 400m3. If the fuel were to be replaced by an equivalent energy of a carbon neutral fuel, such as methanol or liquid H2, determine the following: (a) The change in weight when replacing jet-A by the carbon neutral fuel. (b) As in (a), but for the change in volume. (c) Assume that any extra fuel must be stored in the fuselage, since the wing design cannot be changed. If less volume of fuel is required, then there is no change in airplane design other than that required for the alternative fuel. If extra fuel volume is required, estimate the fraction of fuselage volume required to store the added fuel volume
