This article provides equation for calculating the pressure loss for a fluid and energy for a rolling ball moving in a logarithmic spiral from the action of inertial forces. Classical formulas give incorrect results when calculating coils with a changing twist radius. The calculation of the parameters of the fluid flow in the spiral bend and in the blades of the centrifugal impeller can now be determined only by numerical methods of calculation and, as such, formulas reflecting the energy losses associated with inertial forces do not yet exist. Based on the results of experimental and theoretical work, formulas were obtained that describe the energy losses of a liquid and a ball, when they move along a logarithmic spiral. For the correct derivation of formulas for a moving fluid, it was first necessary to obtain formulas for a rolling ball and a material point. The movement in a logarithmetic spiral is the basis for the movement of particles in a vortex.
