Q6. The mass analysis of a fuel is: carbon 80%; hydrogen 14%; sulphur 3%; water 3%.

Determine EACH of the following:

(a) The theoretical air/fuel ratio by mass

(b) The volumetric analysis of the dry products (i.e excluding H₂O and soluble SO₂) when the fuel is burned completely in 30% excess air

(c) The dew point temperature of the combustion products if the total pressure is 1.0462 bar.

Note: Atomic mass relationships: H = 1; C = 12; O = 16; N = 14; S =32

Air contains 21% oxygen by volume and 23.3% oxygen by mass.
