Colebrook Equation Calculator

The Colebrook Equation requires solving an implicit formula for the friction factor fff in turbulent flow conditions. By iteratively calculating, you can find fff using pipe roughness, diameter, and Reynolds number. For simplified calculations, tools like the Colebrook Equation Calculator or approximations such as the Swamee-Jain equation can provide quicker estimates without iterations. The Colebrook…

Collar Tie Calculator

First, measure the horizontal distance between the rafters and the vertical rise from the collar tie to the roof. Then, apply the formula CT = √(R² + S²) to find the collar tie length. This ensures proper spacing and support for your roof structure. A Collar Tie Calculator is used to calculate the correct length…

collection effectiveness index calculator

Collection Effectiveness Index Calculator

To calculate the Collection Effectiveness Index (CEI), subtract the amount of bad debt (BE) from the total amount billed (B0). Then, divide that result by the difference between the total amount billed (B0) and the amount still outstanding (BS). Multiply the result by 100 to get the CEI as a percentage. The Collection Effectiveness Index…
