γ = ρ g = specific weight (N/m3) The dimensions of equation (5) are energy per unit volume (ft lb/ft3 = lb/ft2 or Nm/m3 = N/m2) The Mechanical Energy Equation in Terms of Energy per Unit Weight involving Heads The mechanical energy equation for a pump or a fan (1) can ...
API stands for the American Petroleum Institute. This organization standardized a unit called API Gravity. If you know the specific gravity of oil, you can use this equation to calculate its API Gravity: 141.5 ÷ Specific Gravity – 131.5 = API Gravity API gravity can also tell us whether the...
γ = ρ g = specific weight of fluid (N/kg, lbf/slug) Equation (2) is often referred to as the "head" because all elements has the unit of length.Note! - the head unit is with reference to the density of the flowing fluid. For other units - like mm Water Column - check ...
weight lossExercise training produces changes in lean and fat weight, yet the original equation that computes target body weight (TBW) assumes that all weight loss is fat. We developed a generalized equation (GTBW) that accounts for various percentages of weight loss due to fat (WF%). GTBW...
The best value for molecular weight is calculated from an extrapolation of ρ/P versus P to zero pressure. In other words, the intercept of line ρ/P versus P is MW/RT. Determine the ρ/P at each pressure. P (Pa)Vmass (m3/g)ρ (g/m3)ρ/P (g/(m3 Pa)) 325,000 0.000622 1606...
Dry air obeys the ideal gas law, where: ρd= density of dry air kg - m-3 Ma= molecular weight of air (28.97 kg / mol) P = barometric pressure (Pa) R = universal gas constant 8.31432 × 103N·m·kmol-1· K-1 T = air temperature (K). ...
For predicting the product of a reaction, the equation balancer is available on the internet. While you enter the reactants, a complete equation will be displayed in a few seconds. The chemical equation product calculator works faster and is the best alternative to manual calculations....

Two reasonable approaches were commonly used to scale surface complexation DLM for Mo sorption on hydrous ferric oxide (HFO). One (Method 1) is on the basis of Fe content (mol sites mole Fe− 1) and the specific surface area (600 m2/g) specified in the original model, regardless of ...
The purpose of this study was to develop and cross-validate anthropometric equations for the estimation of appendicular skeletal muscle mass (ASM) in Chinese adults. A total of 763 adults aged 18-69 years (345 men and 418 women) were recruited from residents living in four regions (Jinan, Gu...
