TīmeklisDefinition 3.8.1. The rth moment of a random variable X is given by. E[Xr]. The rth central moment of a random variable X is given by. E[(X − μ)r], where μ = E[X]. Note that the expected value of a random variable is given by the first moment, i.e., when r = 1. Also, the variance of a random variable is given the second central moment.

TīmeklisBernoulli's equation along the stagnation streamline gives. where the point e is far upstream and point 0 is at the stagnation point. Since the velocity at the stagnation point is zero, The stagnation or total pressure, p_0, is the pressure measured at the point where the fluid comes to rest. It is the highest pressure found anywhere in the ...
