Small heat exchanger design software

There is a small software for designing heat exchangers, as shown in the image below; it gets stuck when calculating heat transfer. In my case, it’s a condensation process involving phase changes, but I don’t understand what r and Ts represent in the formula marked in blue. Does anyone know? Thank you very much!
Based on the screenshot you provided, I believe r represents the ratio of steam to liquid during the condensation process, while Ts represents the surface temperature of the condenser. r is an important parameter in calculating the heat transfer coefficient of the condenser; it depends on the fluid state and flow characteristics inside the condenser. Ts represents the temperature condition of the condenser wall, and it is also one of the key parameters for calculating the heat transfer coefficient. I hope my answer can help you. .
Take a look at the heat exchange design in chemical engineering principles and you’ll understand
Ts must be the saturation temperature, right?
Original poster, could you send the software? Thank you
