Hydraulic Pressure Calculator is a physics/math calculator designed to find the force generated by a piston-cylinder for a specified pneumatic/hydraulic pressure and piston-cylinder bore diameter. Features: - Instant calculation. - Results are copyable to other apps. - Formulas are included as references. - Supports up to 16 decimal places. - Supports various units for each input. - Lightweight app with a small size, optimized for everyday use. The basic principle of the hydraulic press is based on Pascal's law. Pascal's law is a principle in fluid mechanics that states a pressure change occurring anywhere in a confined, incompressible fluid is transmitted throughout the fluid, causing the same change everywhere. Pascal's principle is used in many hydraulic systems, such as hydraulic presses. The Hydraulic Pressure Calculator computes suitable parameters for both pistons in the hydraulic press. Pascal's Law Formula: F₁ = A₁ / A₂ * F₂ p = F₁ / A₁ where: F₁ - Force applied to the first piston. F₂ - Force applied to the second piston. A₁ - Area of the first piston. A₂ - Area of the second piston. p - Pressure of the liquid inside the hydraulic press. Thanks for your support, and please do visit nitrio.com for more apps for your iOS devices.

Verdict

The call

Hydraulic Pressure Calculator and CrapsTracker both sit at 5.0 stars, but that hides the real split: 100% of CrapsTracker's written reviews are positive against 0% of Hydraulic Pressure Calculator's. CrapsTracker also leads on price (Free vs $2.99) and update cadence (every 3 months vs every 27 months). Hydraulic Pressure Calculator's advantage is in-app purchases (none vs 2) and iOS requirement (13 vs 15.0). On rating, ads and device support there is nothing between them.
