A Hydraulic presswith a larger piston of diameter 30cm at a height 1m above the smaller piston of diameter 5cm - Physics - Mechanical Properties of Fluids

Question

A Hydraulic presswith a larger piston of diameter 30cm at a
height 1m above the smaller piston of diameter 5cm is present The
mass on the Smaller piston is 10kg What is the force exerted on the
Load by the larger piston (Density of Oil = 750kgm^-3

Vara · Accepted Answer

Pressure:

It is the force acting normally per unit area

Pressure on the larger piston is equal to the pressure on the
smaller piston + liquid pressure:

F1A1=F2A2+ρghF1πr12=mgπr22+ρghF1=πr12mgπr22+ρgh
=π15×10-3210×9 8π×2
5×10-32+750×9 8×1 =3533 2 N

A Hydraulic presswith a larger piston of diameter 30cm at a height 1m above the smaller piston of diameter 5cm is present.The mass on the Smaller piston is 10kg . What is the force exerted on the Load by the larger piston . (Density of Oil = 750kgm^-3
