Query description
Q1) A pump delivers 40 litres/min to a 90 mm bore/30 mm rod cylinder to raise a load of 200 kg. What’s the strain exerted on the piston?What’s the pace at which the load shall be lifted?How a lot energy is required to raise the load at this pace?Q2)
Think about the hydraulic raise system within the determine under, with 10 mm rod and 50 mm cylinder, used to raise a 500 kg load.
A handpump is getting used with a stroke of seven cm3 per pump actuation. What number of pump cycles can be required to raise the load 100 mm excessive?
Assume you use the hand pump at a pace of zero.three Hz. How lengthy would it not take to raise the load 100 mm excessive?
What’s the work and energy required from the pump operator?
Assume now an electrical motor is getting used that pump at a fee of three litres / min. How lengthy would it not take to raise the load 100 mm?
What’s the work and energy required from the electrical motor?
