Ansys Fluent users can use some cool tricks to simulate near-flame extinction of gas turbines using only a few scalars and a relatively coarse mesh.
A chemist measures the enthalpy change ?H during the following reaction: 2Al (s) + Fe2O3 (s) ? Al2O3 (s) + 2Fe (s) =?H?852.kJ Use this information to calculate ?H in kJ for the following reactions: 3A "Exothermic" process...
how do i use that toolbox in order to define dens_mix as a function? it's value is changing each time the code is actually trying to solve the ODE system, and it is just a sum of 4 parameters: dens_mix= partial_dens(1)+partial_dens(2)+partial_dens(3)+partial_dens(4) ...
Related to this Question Is freezing endothermic or exothermic? Can a chemical reaction be both exothermic and endothermic? Relate both an exothermic and an endothermic reaction to a use within medicine. How is enthalpy used to predict whether a reaction is endothermic or exothermic?
How do enthalpy and entropy relate to endergonic and exergonic reactions? Explain why cellular respiration involves so many molecules and steps based on how life obeys and exploits the Laws of Thermodynamics. How do oxidation/reduction reactions and hydrogenation/dehy...
Steam condensation when it travels on its way to point of use mainly due to exposed surfaces. Leakages (if any) When steam condenses on the wall of an exposed/uninsulated steam pipe, it gives up its enthalpy of evaporation. Proper utilization of steam helps in saving in the input cost of...
Water activity (aw) is similar to equilibrium relative humidity and uses a scale of 0 to 1, instead of 0% to 100%. Enthalpy Enthalpy is the amount of energy required to bring a gas to its current state from a dry gas at 0°C. It is used in air conditioning calculations. ...
All of the experiments were carried out at the German Aerospace Center (DLR) within the HEG (High Enthalpy shock tunnel Göttingen) facility - a reflected-shock wind tunnel, capable of reproducing a wide variety of flow conditions at Mach numbers from approximately 6 to 10. ...
Explain how to use the Born-Mayer equation. Lattice energy: Born Haber cycle is utilized to evaluate a compound's lattice energy. Lattice energy can be related to lattice enthalpy as per the equation given below {eq}{{\rm{\Delta }}_{\rm{G}}}{\rm{U = }}{{\rm{\Delta }}_{\rm{...
What's the difference between heat capacity and enthalpy change? What is the specific heat capacity of substance X when 34.80 g of X is heated from a starting temperature of 20.5^oC to 40.9^oC by 2.54 kJ of energy? Calculate how much heat 32.0 g of water absorbs when it is heated from...
