## The Home Brew Recipe Calculating Program - Kettle Volume Calculator This is the Kettle Volume Calculator. By entering an Initial Volume and Specific Gravity, this calculator can be used to determine what the final specific gravity will be at the final volume entered, or what the final volume should be to hit the final specific gravity entered. The fields on the screen will be prefilled with the values stored for SG and Volume in the current recipe record.

### Fields

• Initial Volume - This field indicates what the Initial Volume should be. Changing this field will cause the Final SG to be recalculated.

• Volume Units - This field is used to indiciate the units used by the calculator. Click on the button in the corner of the field to change the volume units and convert the Initial Volume to the new units.

• Initial SG - This field is used to indiciate the Initial Specific Gravity of the solution. Changing this field will cause the Final SG to be recalculated.

• Final Volume - This field is used to indiciate what the desired Final Volume should be. Changing this field will cause the Final SG to be recalculated.

• Final SG - This field is used to indiciate what the desired Final Specific Gravity of the solution should be. Changing this field will cause the Final Volume to be recalculated.

### Buttons

• Recalc - Click this button to perform calculations.

• Ok - Click this button to exit the calculator.

### Formulas

Here are the formulas used by the kettle calculator.

#### Determining the Final SG

SGf=1+(Vi*(SGi-1))/Vf

Where:

• SGf = Final Specific Gravity
• Vi = Initial Volume
• SGi = Initial Specific Gravity
• Vf = Final Volume

#### Determining the Final Volume

Vf=Vi*(SGi-1)/(SGf-1)

Where:

• Vf = Final Volume
• Vi = Initial Volume
• SGi = Initial Specific Gravity
• SGf = Final Specific Gravity Comments? Question? Email me at rust1d@usa.net
