In this paper, we show that the overall efficiency equations must be developed from an energy balance and show that the simple multiplication of mechanical and volumetric efficiencies can potentially lead to inaccurate results. We then obtain a generalised equation relating the overall efficiency to ...

aIn real systems this dynamics has stochastic character that leads to necessity of representation the generator power as a stochastic process, and the model ofpower balance dynamics of adjustable system is reduced generally to the stochastic differential equation 在实际系统那带领表示法必要发电器力量作为...
A pressure balance analysis has been carried out, along with a dimensionless empirical correlation for the solids holdup in the riser and a semi-empirical equation for the pressure drop across the non-mechanical control valve derived in this work, to successfully predict the stable operating conditi...
TOF values of difffferent electrodes were calculated based on the equation: $$TOF=(J\times A)/(4\times F\times n)$$ (5) whereJ(mA cm−2) is the current density at the overpotential of 400 mV for OER and 200 mV for HER; A is the surface area of electrode; F is the Fa...
Equation 1 represents the subject’s response (subscript i) for one of the five affect measures (affectti) for any given EMA entry (subscript t). Affectti is calculated as the average intercept of one affect measure across all subjects (b0) and two level-1 predictors: the sum of 120 ...
Are you fit?Wouldn't it be great to be able to answer this question simply with a yes or no answer, or to give a simple score of your overall fitness? It is not that easy. First of all, what is fitness? Fitness is hard to define, so it makes this often asked and debated topic...
Knowing the mass of solution deposited onto a 2 Â 2-cm2 quartz substrate, the chitosan content (2 wt%) and the mass reduction in the pyrolysis, the weight of the residual graphene can be estimated by applying the equation 0.02 Â 0.6 Â mass of the solution. In this way, most ...
(The equation is balanced.) Sn2+(aq)+Cd(s) = Sn(s)+ In the following reaction, determine the overall balanced electrochemical reaction, its standard electric potential, and the standard Gibbs energy of the reaction. You may add H2O molecules to balance...
are completely different. Data center amortization periods run from 10 to 15 years while server amortizations are typically in the three year range. Servers are purchased 3 to 5 times during the life of a datacenter so, when amortized properly, they continue to dominate the cost equation. ...
