| 摘 要： | 化工原理教材中,转子流量计流量公式是仿照孔板流量计的推导方法给出的。这种方法认为动能变化是产生压力降的原因,与转子计事实不符。本文运用柏努利方程给出了严格的推导,并给出了实测的结果。

| Abstract: | In scientific literature,the flow rate equation for votor flowmeter is deducted with the reference to the flow rate equation for borehole flowmeter.It is believed,with this approach,that the kinetic energy change is the cause of the decrease in pressure,which is contradictive to the rotor meter.This paper tries to deduct rigorously the equation for the flow rate by using the Bernoulli equation,and to provide the expression of flow rate coefficient.Eventually the test result of the flow rate coefficient is offered. |
