Gas Pipe Sizing Calculator vs Hydraulic Cylinder Calc
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Gas Pipe Sizing Calculator
This utility app simplifies gas pipe sizing by performing calculations based on BTU load, run length, and gas type. It eliminates the need for manual chart and codebook referencing, providing the minimum required pipe size quickly.
- Calculates minimum gas pipe size
- Input BTU load
- Input longest run length
- Select gas type (LP or Natural)
- Designed for low pressure (0.5psi)

Tired of looking at charts and fumbling around in codebooks in order to size gas pipe? This pipe sizing calculator takes all of that work and hassle out of the equation by calculating it for you, based on the total BTU load, length of the longest run, and type of gas. Simply enter the values, select your gas type (LP or Natural) and hit calculate. The minimum size gas pipe needed will be outputted, so you can continue on with your day. Designed for low pressure, 0.5psi

The Hydraulic Cylinder Calculator is a comprehensive tool designed for working with hydraulic cylinders. Users can input parameters such as piston diameter, pressure, and oil flow to calculate various aspects of the cylinder, including areas, volumes, ratio, extraction and retraction forces, velocity, time, and outflow. Features: - On-the-fly calculations based on user-input parameters like piston diameter, pressure, and oil flow. - Results are provided for both the Piston and Rod sides of the Hydraulic Cylinder. - Interactive 3D images illustrate key parameters, enhancing the user's understanding of the Hydraulic Cylinder system. - Support for both Metric and Imperial units. - Copy-able results to clipboard. - Works seamlessly on both iPhone and iPad. - Lightweight, compact app optimized for everyday use. - Ad-free and built with privacy in mind. A hydraulic cylinder, also known as a linear hydraulic motor, is a mechanical actuator used to provide a unidirectional force through a unidirectional stroke. It finds applications in construction equipment (engineering vehicles), manufacturing machinery, and civil engineering. Hydraulic cylinders are powered by pressurized hydraulic fluid, typically oil. The cylinder comprises a cylinder barrel, a piston connected to a piston rod that moves back and forth. The barrel is closed by the cylinder bottom (cap) on one end and the cylinder head (gland) on the other end, where the piston rod emerges. The piston has sliding rings and seals, dividing the cylinder into two chambers – the bottom chamber (cap end) and the piston rod side chamber (rod end/head end). Flanges, trunnions, clevises, and lugs are common mounting options for cylinders. The piston rod also has attachments for connecting the cylinder to the object or machine component it pushes or pulls. The hydraulic cylinder acts as the actuator or "motor" side of the system, while the hydraulic pump serves as the "generator" side, delivering a fixed or regulated oil flow to move the piston. The piston, in turn, pushes the oil in the opposite chamber back to the reservoir. During the extension stroke, assuming the oil enters from the cap end and the oil pressure in the rod end/head end is approximately zero, the force (F) on the piston rod equals the pressure (P) in the cylinder times the piston area (A).
