Hydrogen is used as a fuel in an experimental engine and is burned with stoichiometric oxygen. Reactants enter at a temperature of 25°C and complete combustion occurs at constant pressure. Write the balanced chemical reaction equation.
Calculate:
(a) Fuel–air (fuel–oxygen) ratio.
(b) Equivalence ratio.
(c) Theoretical maximum temperature from this combustion. (Use enthalpy values from a thermodynamics textbook.) [K]
(d) Dew point temperature of exhaust if exhaust pressure is 101 kPa. [°C]
