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:
