Sensible Heat Formula: Q S = 1.08 x cfm x ΔT Latent Heat Formula: Q L = 0.68 x cfm x ΔW where Δh = The change in enthalpy between return and supply air ΔT = The difference between the dry bulb temperature of the return air and the dry bulb temperature of the supply air ...
Heat capacity and enthalpy of transition-metal borides in a broad range of temperaturesPOLLUCITESOL-GELTHERMAL EXPANSIONLIISOMORPHOUS REPLACEMENTThis short note reports the optical characteristics of six newly developed fluorophosphate glasses of the formula (NaPO3) 6-BaF2-ZnF2-RF-PrF3 (RF = LiF,...
That is to say, with condensate flowing exactly down the isotherms, net convection is reduced to zero. Depending on the calculation of the enthalpy change, liquid flow near the steam chamber edge only delivers about 22% of the total energy transferred to the cold oil sands. Ito proposed that...
For other geometries, the general formula (20.39) holds, but the characteristic length is replaced by a hydraulic diameter de = 4 × (cross-sectional area for flow)/(wetted perimeter). For fully turbulent regime in pipes, Re should be larger than 104. The hydraulic design should be such ...
Self-consistent equations for calculating the ideal gas heat capacity, enthalpy and entropy. Fluid Phase Equilibria, 6: 169—179. Self-consistent equations for calculating the ideal gas heat capacity, enthalpy, and entropy are derived based on statistical mechanical formulae and with simplifications ...
with emphasis on humidity and enthalpy as well as wet-bulb temperature, adiabatic saturation temperature, cooling by evaporation, drying, and condensation; and physical properties and other information that must be taken into account before any generalized formula for heat or mass transfer can ...
An extended lattice Boltzmann (LB) equation was developed for the simulation of the phase-change problem governed by the heat conduction equation incorporated with enthalpy formation. Mathematical consistency between the proposed extended LB equation and the governing equation was accomplished by the Chapma...
