Question 3 A sheathed thermocouple is placed in a combustion chamber to measure the temperature of the gases at a certain point in the process. The thermocouple reading is 1110K and the inside wall temperature was measured at 1008K. The thermocouple has a surface area of 10 mm2 . (a) A pitot probe is used to measure the velocity of the gas stream in the vicinity of the thermocouple tip. It measures a difference in static and dynamic pressure of...

Determine what is the temperature of the hot combustion gas that is produced in the engine...

Determine what is the temperature of the hot combustion gas that is produced in the engine of a butanol (C4H9OH)-burning bus that uses ambient air for the combustion. Tip: write the balanced stoichiometric equation for the combustion of butanol assuming air is composed of 80% N2 and 20% O2 by volume, and derive the energy balance of the combustion. Atomic weights: C-12, H-1, O-16, N-14. For butanol: cp = 2 kJ/kg/°C; cv = 1.75 kJ/kg/°C; heat released by combustion, or...

Temperatures of gases inside the combustion chamber of a four‑stroke automobile engine can reach up to 1000 ∘C.1000 ∘C. To remove this enormous amount of heat, the engine utilizes a closed liquid‑cooled system that relies on conduction to transfer heat from the engine block into the liquid and then into the atmosphere by flowing coolant around the outside surface of each cylinder. Suppose that, in a particular 55‑cylinder engine, each cylinder has a diameter of 8.50 cm,8.50 cm, a height...

Hot combustion gases enter the nozzle of a turbojet engine at 260 kPa, 747°C, and 80 m/s, and they exit at a pressure of 85 kPa. Assuming an isentropic efficiency of 92 percent and treating the combustion gases as air, determine (a) the exit velocity and (b) the exit temperature. Answers: (a) 728 m/s, (b) 786 K

Hot combustion gases enter a gas turbine at 0.8 MPa and 0.538 m3/kg at a rate of 2.1 kg/s, and exit at 0.1 MPa and 2.29 m3/kg. Heat is lost from the turbine to the surroundings at a rate of 150 kW and the internal energy decreases 904 kW in the process. What is the power output of the gas turbine? (Assume no change in velocity or elevation across the turbine.)

The following data show the rate constant of a reaction measured at several different temperatures. Temperature (K) at 310 has a rate constant (1/s) of 4.65×10^−2 . Temperature (K) at 320 has a rate constant (1/s) of 0.139. Temperature (K) at 330 has a rate constant (1/s) of 0.386. Temperature (K) at 340 has a rate constant (1/s) of 1.01. Temperature (K) at 350 has a rate constant (1/s) of 2.52. Part A) Use an Arrhenius plot to determine the...

1. Obtain a linear regression equation for the data to predict the mean temperature values for any given CO2 level. How good is the linear fit for this data? Explain using residual plot and R-square value. To draw residual plot, compute the estimated temperatures for every value of the CO2 level using the regression equation. Then compute the difference between observed (y) and estimated temperature values (called residual; ). Plot the residuals versus CO2 level (called a residual plot). 320.09...

Data containing n=130 observations of new born body temperatures produced a mean body temperature of 98.249° F. If we know that the standard deviation of body temperature varies by .733° determine if there is evidence to suggest that new born babies have a body temperature different then the adult average of 98.6° F. Use an alpha level of .01 1) State the hypothesis: Ho: Ha: (do not put spaces in these, use the symbols above to copy and paste as...

(a) Dry saturated steam at a temperature of 180ºC is to be produced in a fire tube boiler from the cooling of 50 000 kg h–1 of flue gases from a pressurised combustion process. The gases enter the tubes of the boiler at 1600ºC and leave at 200ºC. The feed water is externally preheated to 180ºC before entering the boiler. The mean specific heat capacity of the flue gases is 1.15 kJ kg–1 K–1. The latent heat of vaporisation...
