Heating Pipe Size

Features
Read full description

Estimate required pipe diameter of a closed hydronic heating or cooling system in an instant and calculate pressure drop to determine required circulation pump characteristics (flow and head). Easy to use, quick and accurate results. Enter the required heating or cooling output and water flow and return temperatures. Choose pipe material. The recommended pipe diameter is already there, presented as a standard DN. Additionally, choose the recommended or a custom pipe diameter and specify pipe section length and fittings. Results include water flow rate, velocity, pressure drop and pressure drop per 100 m of straight pipe and can be used to determine the parameters of a circulation pump. ## Features: - Simple to use; - Suitable for hydronic (water-based) heating and cooling systems; - Suitable for a large range of heating and cooling outputs; - Predefined pipe materials; - Water temperature range from 1 to 99 ºC; - Completely independent from any manufacturers; - No login needed, no data connection needed; - No data collection; - No subscriptions, one-time purchase only; - Very quick calculation with no delays; ## Possible uses of the application: - Quickly estimate required pipe diameter when designing a hydronic (water-based) closed heating or cooling system. - Quickly determine circulation pump requirements (flow and head), whether it be a new system or a replacement pump. ## Notes: - It is recommended to calculate every section of the piping system separately and additionally check the whole system pressure drop. - The application is only useful for calculations of hydronic (water based) closed heating or cooling systems. Other systems and media are not supported. - Only metric units are supported. - The application, while accurate, is not meant as a complete replacement of specialized software for heating and cooling system design. The application doesn't require data connection. It doesn't require and doesn't collect any personal data. It also doesn't contain third-party ads or code. Also: no in-app purchases, no subscriptions.

About

Stress Strain Calculator

Features
Read full description

Stress, Strain Calculator is a physics/math calculator designed to find stress, strain, or modulus of elasticity quickly and easily. Features: - Instant calculations. - Results can be copied to other apps. - Formulas are included as references. - Supports up to 16 decimal places. - Supports various units for each input. - Works seamlessly on both iPhone and iPad. - Lightweight, compact app optimized for everyday use. - Ad-free and built with privacy in mind. Stress, strain, and Young's modulus are all factors linked to the performance of a material or object in a particular setting. Stress: Simple engineering stress is similar to pressure in that it is calculated as force per unit area. Stress is a physical quantity closely associated with 'internal force.' It measures the average amount of force exerted per unit area over a material. The maximum amount of stress a material can withstand before breaking is called breaking stress or ultimate tensile stress. Strain: Strain is the response of a system to an applied stress. When a material is loaded with a force, it produces stress, which causes the material to deform. Engineering strain is defined as the amount of deformation in the direction of the applied force divided by the initial length of the material. Formula : ε = (L₂ - L₁)/L₁ σ = F/A E = σ/ε Where, F = Force A = Area L₁ = Initial Length L₂ = Final Length ε = Strain σ = Stress E = Young's modulus Thank you for your support.

Verdict

The call

The clearest difference is price: Stress Strain Calculator at $2.99 against Heating Pipe Size's $5.99. Stress Strain Calculator also leads on iOS requirement (13 vs 26.0). Heating Pipe Size's advantage is update cadence (every 15 months vs every 31 months). On ads, in-app purchases and device support there is nothing between them.
