aThe relationship shown in the first equation signifies that the effective power conversion in the case of viscous flow consists of a part from the pressure distribution on the bucket surface and a part from the direct frictional force. 在first等式signifi显示的关系ES有效功率转换在黏fl...
aThe power given in equation (26) for the frictionless flow depends on the operating condition and especially on the specific circumferential velocity, which is defined by 在式给的力量(26)为无磨擦的flow取决于操作条件,并且特别是在specific周围速度,是defined [translate] ...
Thus, the equation y''+x^2y=0 becomes 2c_2+6c_3x+∑limits _(n=0)^(∞ )[(n+4)(n+3)c_(n+4)+c_n]x^(n+2)=0. So c_2 = c_3 = 0 and the recursion relation is c_(n+4)=- (c_n)((n+4)(n+3)), n = 0,1,2, …. But c_1=y'(0)=0=c_2=c_3 and by...
If I have the equation of X raised to the power of X is Y, how do I calculate X if I am given Y? This can't be done using elementary functions. You can use the Lambert W function to solve y=xxy=xx. Take the natural log of both sides, then replace xx with xln...

If the velocity and pressure are known for the initial time t = 0, then the state of the fluid over time can be described by the Navier-Stokes equations for incompressible flow:Equation 1Equation 2where is the (constant) fluid density, is the kinematic viscosity, and F = (fx ,...
The confusion matrix shows how many predicted instances are for each class, indicating the model performance39. The metrics’ equations are shown in equation 1. The accuracy is evaluated using (1a), the ratio between the summation of all the correct predictions. Which are the truly predicted ...
a哦,是这样阿,中国的。 Oh, is this Arab League, China.[translate] aI am very sorry! 我非常抱歉![translate] aTo determine the power factor (PF) integrated LED lamps (subsections 6.1.7., 6.2.7.), you must apply the following equation: 要确定功率因素(PF)集成了LED灯(分部6.1.7。, 6.2...
Generally, there are two methods for runoff process research in ungauged basin [6]: One is to establish a watershed hydrological model that only contains physical parameters. Since the model parameters may be measured, they can be used directly in the areas without data. The alternative option ...
