Ball Drop

Ball-Drop Multistage Fracturing

Equation used to calculate ball speed in fluid:

V=sqrt(4*g*d(rhos-rho)/rho/(3*Cd))

where

V - Velocity

g - gravitational accelerations

d - diameter of spherical object

rhos - density of object

rho - density of fluid

Cd - drag coefficient (Drag coefficient - follow wikipedia), calculated as:
