ABSTRACT

O, but its molar mass is 180, what is its formula?

Problem 4.2:

Two gaseous fuels A and B have molecular weights and molar heating values such that M

/M

=

2.25 and HV

/HV

=

1.5. If the heat release rate of A is

and B is

. Then

/

=

Problem 4.3:

The ultimate analysis of a fuel provides C

=

37.5%, H

=

12.5%, O

=

Problem 4.4:

Coal with the chemical formula CH releases volatile matter (VM) that has an empirical formula of CH

. The volatile matter percentage on a mass basis is

Problem 4.5:

To develop a new fuel (NF) for power production, the cost of NF in comparison to an existing fuel (say, natural gas [NG]) must be considered. What are the best units to express the cost of NF and NG? Cost per kg? Cost per GJ?

Problem 4.6:
