# 依泊肃叶方程在线计算

V = Volume per Second
P = Pressure Difference Between The Two Ends
R = Internal Radius of the Tube
n = Absolute Viscosity
L = Total Length of the Tube

### 计算公式

$$v=\frac {π×P×R^4}{8×n×L}$$

$$π=3.1415$$

• V = 每秒的容量，米/秒
• P = 两端的压力差，mmHg
• R = 管的内部半径，米
• n = 绝对粘度，百分之一的依泊肃叶
• L = 该管的总长度，米
