【Abstract】 Taking the stochastic data of 10 groups of orifice plate flow qv and orifice platepressure difference as an example and using the mathematical statistics method, it is provedthat the normal distribution is appeared in the orifice plate flow.The general computationmethod for the orifice plate coefficient k is derived. Finally,it is also proved that the linearregression effect is very obvious.更多还原
