The Dry Weight of Solid is the weight of dry solid present in the system in the drying mass transfer operation, excluding any moisture content.
The calculator uses the formula:
Where:
Explanation: This formula calculates the dry weight of solid based on the amount of free moisture that can be removed and the free moisture content ratio.
Details: Accurate calculation of dry weight is crucial for drying operations, material balance calculations, and process optimization in various industrial applications.
Tips: Enter free weight of moisture in kg and free moisture content as a ratio (kg moisture/kg dry solid). Both values must be positive numbers.
Q1: What is free moisture content?
A: Free moisture content is the ratio of the amount of free moisture present in the solids to the weight of dry solid.
Q2: How is free weight of moisture different from total moisture?
A: Free moisture is the moisture above equilibrium moisture content that can be removed by drying, while total moisture includes both free and bound moisture.
Q3: What are typical units for these measurements?
A: Weight is typically measured in kg or g, while moisture content is expressed as a ratio or percentage.
Q4: When is this calculation most useful?
A: This calculation is particularly useful in drying operations, food processing, pharmaceutical manufacturing, and other industries where moisture removal is critical.
Q5: What factors can affect the accuracy of this calculation?
A: Measurement errors in moisture content determination, non-uniform moisture distribution, and variations in material properties can affect accuracy.
