Inputs (SI units)

Mass m	500 kg
Velocity v	0.5 m/s
Cycles C	30 /h

Calculation

Kinetic energyE1 = ½·m·v² = ½·500·0.5²	62.5 J
Drive energyE2 = m·g·s = 500·9.81·0.050	245.3 J
Energy per cycleE3 = E1 + E2	307.8 J
Energy per hourE4 = E3·C = 307.8·30	9 233 J/h
Effective massme = 2·E3 / v²	2 462 kg

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