Pipe Calculator vs Lumen Calculator Usage & Stats

Pipe Calc contains no ads! It is a simple app to calculate rapidly your pipe or duct diameter When you are in a meeting or project discussion you can immediately calculate the size of the needed pipe or duct. This app is simple to use. It does just what it needs to do. There are no unnecessary features, which can confuse you. 1. It calculates the pipe diameter for steam or water pipe, the steam parameters are calculated by the app. The calculated values may be slightly inaccurate however it is negligible for sizing. 2. It calculates the air ducts round or rectangular for a given amount of air with max allowable velocity you can define. 3. For a given heat dissipation it calculates the needed amount of cooling water or cooling air. 4. In the settings you have the choice between different units. You can adjust the stored nominal diameters for each application.

Lumen Calculator

The Lumen Calculator is a physics/math calculator designed to swiftly and easily convert between lumens, lux, and candelas. Features: - Instant calculation - Results are copyable to other apps - Formulas included as references - Supports up to 16 decimal places - Supports various units for each input Definitions: - Lumens: Unit of luminous flux, representing the total amount of light emitted by a source. - Lux: Measure of surface illumination, indicating how much light is received by a surface. - Candelas: SI units of luminous intensity, representing light emitted from a source in a particular direction per steradian. Note: Candelas measure the light emitted in a specific direction, while lux measures the light received per unit area. One steradian, the area of the receiving surface, is equal to the squared distance between the source and the receiver. Formulas: 1. Lumens = Candelas * Ω (For a specific angle) 2. Lumens = Candelas * 2π * [1 - cos(θ/2)] 3. Lux = Lumens / Area 4. Lux = Candela / Distance² Where: Ω = 2π * [1 - cos(θ/2)] Ω = 4π Thanks for your support, and please visit nitrio.com for more apps for your iOS devices.
