Constant Drying Time from Initial to Final Moisture Content Solution

STEP 0: Pre-Calculation Summary

Formula Used

Constant Rate Drying Time = Dry Weight of Solid*(Initial Moisture Content for Constant Rate Period-Final Moisture Content for Constant Rate Period)/(Drying Surface Area*Rate of Constant Drying Period)
t_c = W_S*(X_i(Constant)-X_f(Constant))/(A*N_c)
This formula uses 6 Variables

STEP 1: Convert Input(s) to Base Unit

Dry Weight of Solid: 100 Kilogram --> 100 Kilogram No Conversion Required
Initial Moisture Content for Constant Rate Period: 0.49 --> No Conversion Required
Final Moisture Content for Constant Rate Period: 0.15 --> No Conversion Required
Drying Surface Area: 0.1 Square Meter --> 0.1 Square Meter No Conversion Required
Rate of Constant Drying Period: 2 Kilogram per Second per Square Meter --> 2 Kilogram per Second per Square Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

t_c = W_S*(X_i(Constant)-X_f(Constant))/(A*N_c) --> 100*(0.49-0.15)/(0.1*2)

Evaluating ... ...

t_c = 170

STEP 3: Convert Result to Output's Unit

170 Second --> No Conversion Required

FINAL ANSWER

170 Second <-- Constant Rate Drying Time

What is Constant Rate Drying Period?

The constant rate drying period is a stage in the drying process where the rate of moisture removal from the material is constant and is determined by the drying conditions, such as temperature, humidity, and airflow. During this period, the moisture on the surface of the material is rapidly removed, resulting in a steep decline in the moisture content of the material.

How to Calculate Constant Drying Time from Initial to Final Moisture Content?

Constant Drying Time from Initial to Final Moisture Content calculator uses Constant Rate Drying Time = Dry Weight of Solid*(Initial Moisture Content for Constant Rate Period-Final Moisture Content for Constant Rate Period)/(Drying Surface Area*Rate of Constant Drying Period) to calculate the Constant Rate Drying Time, The Constant Drying Time from Initial to Final Moisture Content formula is defined as the time taken for drying in the constant rate period based on the specific drying conditions for drying from initial to final moisture operation. Constant Rate Drying Time is denoted by t_c symbol.
