The calculation of the heat load was biased and the results were compared with those calculated by the THS and HSS. The results showed that the winter load calculated was 251.3 kW by using HSS. The heat index per unit area in winter was 49.9 W/m2. The heat index per unit area was ...
循环水换热计算(Calculation of heat transfer of circulating water) 1. What are the basic properties of water and steam? Answer: the basic physical properties of water and water vapor are specific gravity, specific volume, latent heat of vaporization, specific heat, viscosity, temperature, pressure,...
aThe new procedure allows the calculation of a more timely index by using projected values for series which are not yet available in the publication period, along with the latest values for the stock market index and the yield spread, which are available sooner. 新的做法通过使用计划的价值允许一...
A method for the accurate calculation of the P4SR Index of heat stress by computer is described. Analysis shows that, although the P4SR Index is basically sound, at least one serious imperfection exists, namely, the effect attributed to an air speed of 75 ft/min. The only previously describ...
indexSetsPerDof = (topWall,) ) I think this should do the work (please correct me if there is something I missed). The calculated heat flow at the bottom boundary with temperatureField.fn_gradient seems indeed smaller than heat flow at the top, but still far away from zero, as shown ...
Finally, this paper proposes the normalization method of the overall optimum and calculates the remotely sensed ecological index for each year on this basis. The analysis of the obtained results shows that the first principal component under the calculation by this method has a higher contribution ...
this part is wrong also. The reaction produces 53.4kJ of heat when 1 mol of HNO3 with 1 mol of KOH. So when 0.03 mol of HNO3 reacts with 0.034 mol of KOH, you do not get 0.064 * 53.4 kJ of heat. You only get 0.03 * 53.4 kJ of heat (since HNO3 will be the limiting reagent...
A recursive calculation of reflection and transmission coefficients based on classical Fresnel formulas is performed for dielectric-metal-dielectric-type screens. The metal is assumed to be silver, while the dielectric layer is formed of semiconductors or dielectrics with index of refraction varying from...
Decay heat Spent nuclear fuel Uncertainty quantification Back-end cycle 1. Introduction This paper presents the uncertainty quantification (UQ) of the decay heat for a pressurization water reactor (PWR) fuel assembly (FA) using the STREAM/RAST-K two-step method. The importance of the intermediate...
To work out the change in enthalpy at 25c(298K) I simply minis the heat formation of the product minus the reactants producing: -72.6 – 0 – 30.9 = -103.5kj mol^-1 Then to work out the enthalpy change of at 65(999k) = enthalpy change at 298K + change in heat capacity x (99...
