Drying Surface Area based on Initial to Final Weight of Moisture for Constant Rate Period Solution

STEP 0: Pre-Calculation Summary

Formula Used

Drying Surface Area = (Initial Weight of Moisture for Constant Rate-Final Weight of Moisture for Constant Rate Period)/(Constant Rate Drying Time*Rate of Constant Drying Period)
A = (M_i(Constant)-M_f(Constant))/(t_c*N_c)
This formula uses 5 Variables

Variables Used

Drying Surface Area - (Measured in Square Meter) - The Drying Surface Area is the total area in the drying mass transfer operation i.e. exposed in contact with the drying medium.
Initial Weight of Moisture for Constant Rate - (Measured in Kilogram) - The Initial Weight of Moisture for Constant Rate Period is the amount of moisture in kg present in the wet solid initially for drying operation.
Final Weight of Moisture for Constant Rate Period - (Measured in Kilogram) - The Final Weight of Moisture for Constant Rate Period is the amount of moisture in kg present in the solid after the completion of drying operation.
Constant Rate Drying Time - (Measured in Second) - The Constant Rate Drying Time is the time taken for drying operation in the constant rate period.
