| Vibrating surface area, A | 1.38 · 10−3 m2 |
A is given by the sum of three areas: (1) the lateral area of a truncated cone having D i-nozzle and D f-nozzle as bases and L act as height; (2) the lateral area of a truncated cone with D tip and D o as bases and H tip as height; (3) the annulus area with D tip and D f-nozzle, respectively as external and internal diameter; |
