1. What is the Condensation Number?

The Condensation Number is a dimensionless number that helps resolve equations in terms of film Reynolds number, which is important in determining condensation behavior in heat transfer applications.

2. How Does the Calculator Work?

The calculator uses the Condensation Number formula:

\[ Co = (C^{\frac{4}{3}}) \times \left(\frac{4 \times \sin(\Phi) \times \left(\frac{A_{cs}}{P}\right)}{L}\right)^{\frac{1}{3}} \times (Re_f)^{-\frac{1}{3}} \]

Where:

\( Co \) — Condensation Number (dimensionless)
\( C \) — Constant for Condensation Number
\( \Phi \) — Inclination Angle (radians)
\( A_{cs} \) — Cross Sectional Area of Flow (m²)
\( P \) — Wetted Perimeter (m)
\( L \) — Length of Plate (m)
\( Re_f \) — Reynolds Number of Film

Explanation: The equation calculates the condensation number based on geometric parameters and flow characteristics, providing insight into condensation behavior.
