Time needed (in sec) taken by the hydraulic cylinder to get the required lift

Friends
One clarification please help me out in this

Piston diameter: 125mm
Piston rod diameter: 90mm
Weight of the object to be lifted : 3000kg
Hydraulic oil used : HLP46
Required stroke length is 1meter

My question is what would be the approximate time (in sec) taken by the hydraulic cylinder to get the required lift of 1meter.


I dont have not even a single idea in this concept.. Please help me out in this

    What is the efficiency of the hydraulic pump?

    The speed of the piston is directly proportional to the capacity of the hydraulic pump
    example:
    D = 125mm
    A = (0.125 * 0.125) * PI / 4 = 0.0123 m2
    If the oil flow rate of 1 l / s Q = 0.001 m3 / s
    and the efficiency of the actuator = 0.95
    the speed v = 0.95 Q / A = 0.001 * 0.95 / 0.0123 = 0.0772 m / s

    So time to raise about 1 m is t= 1/0,0772 = 12.9 s
