Question
The liquefied petrolieum gas(LPG) is composed of 80% C;Hg and 20%
C4H10 in mass basis.
(1). Determine the molar fraction of C3H8 and C4H10 in LPG.
(2). Determine the stoichiometric air fuel ratio of the LPG.
(3). Determine the lower heating value of LPG in kJ/m³ at 25°C and 100
kPa.
(4). LPG is mixed with excess air to burn in a boiler at 100 kPa.
The
CO2 in burned gas is 7% on dry basis. Determine the equivalence ratio of
the mixture.
