## Flow Application Capacity Calculators

### Liquid Flow Rate (GPM) Formula

To calculate the liquid gallon per minute flow rate that is required to select the appropriate liquid control valve and flow meter, use the following formula:

Boom Width x Ground Speed x Application Rate (GPA) x 0.00202

Adjust the cells to calculate the GPM Flow

### NH_{3} Flow Rate (lbs/hour) Formula

To calculate NH_{3} flow rate (lbs/hour), use the following formula:

Implement Width x Ground Speed x Application Rate (lbs/NH_{3} per acre) x 0.1212

Adjust the cells to calculate the lbs/Hour

### Hydraulic Oil Flow Rate Formula (assumes 1:1 gear ratio)

To calculate hydraulic oil flow requirements to select the optimal hydraulic control valve for use with a hydraulic motor, use the following formula:

Hydraulic motor in^{3}/rev x motor RPM required divided by 231

Adjust the cells to calculate the oil GPM required

### Hydraulic Motor RPM Formula (assumes 1:1 gear ratio)

To calculate motor RPM required to achieve maximum application rate enter values for pounds per 1 REV, max application rate, ground speed, and spread width.

Adjust the cells to calculate the oil GPM required

### Hydraulic Oil Flow Rate Formula (assumes 1:1 gear ratio)

To calculate hydraulic oil flow requirements to select the appropriate hydraulic control valve for use with a hydraulic motor, use the following formula:

Hydraulic motor in^{3}/rev x Motor RPM required divided by 231

Adjust the cells to calculate the oil GPM required

### Hydraulic Motor RPM Formula (assumes 1:1 gear ratio)

To calculate motor RPM required to achieve maximum application rate enter values for seeds dropped per 1 REV of planter row unit, max application rate, ground speed, and row spacing.

Adjust the cells to calculate the max motor RPM required
