How to calculate
Apply equal fluid pressure to two pistons to find output force and mechanical advantage; the piston areas must use the same square-centimetre unit.
Output force = F*B/A N; Area ratio = B/A; Fluid pressure = F/(A/10000) Pa
Worked example
Input force (N): 100; Input piston area (cm²): 10; Output piston area (cm²): 100.
Output force: 1,000 N; Area ratio: 10 ; Fluid pressure: 100,000 Pa.
Assumptions and limits
Apply equal fluid pressure to two pistons to find output force and mechanical advantage; the piston areas must use the same square-centimetre unit. Ideal incompressible fluid with constant density. Gauge pressure excludes atmospheric pressure; the hydraulic press ignores friction and losses.
