Inputs (SI units)

Mass m	250 kg
Velocity v	0.6 m/s
Friction μ	0.2
Cycles C	120 /h

Calculation

Kinetic energyE1 = ½·m·v² = ½·250·0.6²	45 J
Drive energyE2 = μ·m·g·s = 0.2·250·9.81·0.025	12.3 J
Energy per cycleE3 = E1 + E2	57.3 J
Energy per hourE4 = E3·C = 57.3·120	6 870 J/h
Effective massme = 2·E3 / v²	318 kg

s = stroke of the selected model · g = 9.81 m/s²
