Benzene gas (C6H6) at 25° C and 1 atm, enters a combustion chamber operating at steady state and burns with 95% theoretical air entering at 25° C and 1 atm. The combustion products exit at 1000 K and include only CO2 , CO , H2O , and N2.

Determine:
The mass flow rate of the fuel, in kg/s, to provide heat transfer at a rate of 1000 kW

The mass flow rate of the fuel, in kg/s =

Explanation:

The actual balanced equation for the combustion reaction can be written as :

At 95% theoretical air entering at 25° C and 1 atm, the equation of the reaction can be represented as :

The Energy rate formula can be use to determine the mass flow rate of the fuel and which is given as:

from ideal gas table at respective amount for each compound; we have:

Given that;

The combustion products exit at  1000 K =

From the ideal gas tables M = 78.11 kg/kmol

∴

∴ The mass flow rate of the fuel, in kg/s =

diy

explanation:

answer:

d. attempt to find the owner, then leave your information if you cannot find them.

explanation:

d. represents both (b) and (c).

more logical as well.

b and c are to complicated.

glad i could , give me a follow, so if you need with any other question, im here.
