Determine the adiabatic combustion temperature at constant
pressure and at constant volume for two of the fuels of personal
choice. Graphically show that this corresponds to the product
temperature where the heat of reaction is zero.
Propose a reasonable value for pressure, volume, and temperature
etc., the heat transfer Q, work done W, and internal energy change
ΔU for each of the steps in the Carnot cycle and thermal
efficiency.
For a constant-volume stoichiometric propane-air mixture
initially at 298K, determine the adiabatic flame temperature and
final pressure assuming constant specific heats evaluated at
298K.
For
heat transfer
1. how would one calculate the temperature of a probe at a
distance X from wall.
Thermal conductivity is known
Diameter is known
Extenernal ambient temperature is known
Surface heat transfer coefficient is known
Gas temperature is known
Radiative heat transfer is negligible
2. How would one calculate rate at which energy is gained by
convection to the probe (using above information)
3. How to determine minimum length of probe to be considered
thermally infinite
Can someone please explain how can someone find how to
find the adiabatic flame temperature in Kelvin when liquid methane
reacts with liquid oxygen?
Please show the calculations.
