Winch calculation

The higher the speed (at a given load), the more power we need. The calculations behind this look as follows: P (kW) = F (N) x V (metres/min) / 1020 x 60 In which P = power in kW, F = Force (line pull) in Newton, V = Line speed in metres/min, 1020 is a constant and 60 is a translation from minutes into seconds (Nm/sec).
