The Dry Weight of Solid is the weight of dry solid present in the system in the drying mass transfer operation. It represents the mass of solid material excluding any moisture content.
The calculator uses the formula:
Where:
Explanation: The formula calculates the dry weight of solid by dividing the equilibrium weight of moisture by the equilibrium moisture content ratio.
Details: Accurate calculation of dry weight of solid is crucial for drying process design, moisture content analysis, and quality control in various industrial processes including food processing, pharmaceuticals, and chemical manufacturing.
Tips: Enter the equilibrium weight of moisture in kilograms and the equilibrium moisture content as a dimensionless ratio. Both values must be positive numbers greater than zero.
Q1: What is equilibrium moisture content?
A: Equilibrium moisture content is the ratio of the weight of moisture in equilibrium with the solid to the weight of dry solid.
Q2: When is this calculation typically used?
A: This calculation is commonly used in drying operations, moisture analysis, and process engineering where precise measurement of dry solid weight is required.
Q3: What units should be used for input values?
A: Equilibrium weight of moisture should be in kilograms (kg), while equilibrium moisture content is a dimensionless ratio.
Q4: Can this formula be used for all types of solids?
A: Yes, this formula is applicable to various solid materials as long as the equilibrium conditions are properly established and measured.
Q5: What if the equilibrium moisture content is zero?
A: The equilibrium moisture content cannot be zero in practical applications as it would make the calculation undefined. Always ensure XEq > 0.
