A hydraulic press is used to raise an 80 kN cargo truck. If oil of specific gravity 0.82 acts on the piston under pressure of 10Mpa. What is the diameter of piston required?
hydraulic press has a diameter ratio between the two pistons of 8:1. The diameter of the larger piston is 600 mm and it is required to support a mass of 3500 kg. The press is filled with a hydraulic fluid of specific gravity 0,8. Calculate the force required on the smaller piston in N to provide the required force; (a) when the two pistons are level, (b) when the smaller piston is 2.6 m below the larger piston.
The tank depicted in in the diagram is located at an oil refinery. There is rectangular hatch locatedon one side that gives access for maintenance. The company will be replacing the hatch door andhas hired you to assist with the design requirements.II. (M1) The client is procuring a new hydraulic lifting jack. The jack is rated to lift 2000kg. Given thatthe diameter of the pumping piston is 25 mm and the lifting piston is 40 mm, calculate for theclient:a) The force needed on the pumping piston to raise the max load.b) The pressure in the oil.c) If the pumping piston moves 1cm with every pump, what distance does the lifting piston move
