1 kmol of gas Ethane is burned with 175 percent theoretical air in a steady flow combustion chamber. An analysis of the combustion gases reveals that all the hydrogen in the fuel burns to H2O but 95 percent of the Carbon burns to CO2 with the remaining 5 percent forming CO. Treating the air as dry air, determine; (a)The balanced combustion equation. (b)The air-fuel ratio. (c)The amount of heat transfer (in kJ/kg of fuel) from the combustion process if the...
Question 4 Benzene gas (C&H6) at 25 deg C is burned during a steady flow combustion process with 95% theoretical air that enters the combustion chamber at 25 deg C. All the hydrogen in the fuel bums to H20, the carbon bums to CO and CO. f the products leave at 1000 K, determine a the mole fraction of the CO in the products [101 the heat transfer from the combustion chamber per kmol of fuel (15] b.

Liquid propane (C_3H_8) enters a steady-flow combustion chamber at 25 Degree C, and 6 atm at a rate of 0.8 kg/min. It is burned with 150 percent excess air that is compressed and preheated to 400 K and 6 atm before entering the combustion chamber. The products of the combustion enter a gas turbine at 1200 K and 6 tam and leave at 700 K and 1 atm. The adiabatic efficiency of the turbine is 80%. The combustion process is...
Propane burns completely with 150% excess air during a steady-flow combustion process. If both the reagents and the products are kept at 25 ° C and an atmosphere and the water in the products exists in liquid form, determine : to. A.The real balanced equation B. Heat transfer (kJ / kmol) C. Adiabatic flame temperature (K)

Week 4 Process 1: Consider the process below: Water in Combustor Steam Generator Gas In Gas Out Combustor exit Steam Out A methane (CH) and air mixture is burnt in the combustor then the heat is recovered to produce steam. The CHa/air mixture comes in at 25°C and contains 10 kg/h of CH4 and 500 kg/h of air (assume 79% Nitrogen (N2) and 21 % Oxygen (O2)). The final outlet gas leaves at 100 °C. The combustion reaction follows the...
Methane gas is burned with 30 percent excess air. This fuel enters a steady- flow combustor at 0.8 atm and 25oC and is mixed with the air. The products of combustion leave this reactor at 0.8 atm and 1600 K. Determine the equilibrium composition of the products of combustion and the amount of heat released by this combustion in kJ/kmol methane. Use data from the tables CH 25°C CO2, H3O chamber NO.

I need help to write a nice introduction for experiment 6 please ( no hands write ) typing Thank you HEAT TREATMENT OF STEELS EXPERIMENT 6 EXPERIMENT 6 HEAT TREATMENT OF STEELS THEORY The Effect of Cooling Rate One of the most convenient methods for controlling the properties of a given steel, i.e., a steel whose composition is already fixed, consists of austenizing the steel and ten cooling to room temperature at some predetermined rate. A variation of cooling rates...
