Calculation of Potential Energy:

The potential energy of the accumulator can be calculated as follows:

Potential Energy = Force x Distance

Force = Total Load on Ram - Frictional Effects
= 300 kN - 2% of 300 kN
= 294 kN

Distance = Effective Stroke of Ram
= 3 m

Potential Energy = 294 kN x 3 m
= 882 kNm

Calculation of Power:

The power delivered by the accumulator can be calculated using the formula:

Power = Potential Energy / Time

Time = 49 seconds

Power = 882 kNm / 49 s
= 18 kW

Therefore, the total power delivered by the accumulator when the ram falls through its full stroke in 49 seconds is 18 kW.
