Note: Hi! I already have answers as I have computed it earlier. May I confirm from you whether my computations were right or wrong because I do not have any key answers. I only wrote what is missing per letter and I did not list the given values anymore such as in [analysis of VCM where S = 0.57] . Please see below. Thank you for your help in advanced!

With a basis of 100 kg fuel

a. VCM = 35.34 kg 

b. 

C = 46.26 kg  where 22.91 kg (FC) and 23.35 kg (C in VCM) 

H = 5.55 kg 

O = 39.12 kg 

% net H = 0.66 

c. 

CW = 9.46 kg 

d. 

GCV = 25.18 MJ/kg VCM
