## What is a Dripline Calculator?

A drip line calculator helps users calculate the number of emitters and the total length of drip line needed for their field.

Dripline is a type of irrigation system that delivers water directly to the roots of plants through a network of small tubes with emitters, which are small devices that control the flow of water.

It is an efficient way to irrigate plants because it allows water to be delivered directly to the root zone, reducing water loss due to evaporation and ensuring that plants receive the water they require.

## How to use this calculator?

To use this calculator, you will need to input the following information:

• Field Size (sq ft): This is the size of the field you want to irrigate, in square feet. You can calculate the size of your field by measuring the length and width of the area and multiplying them together. For example, if your field is 10 feet long and 20 feet wide, the field size would be 200 sq ft.
• Emitter Spacing (in): This is the distance between the emitters on your drip line, in inches. Emitter spacing refers to the distance between the centers of two adjacent emitters. It is important to choose an appropriate emitter spacing for your field, as it affects the distribution of water and the overall efficiency of your irrigation system.
• Flow Rate (gph): This is the flow rate of your irrigation system, in gallons per hour. The flow rate refers to the amount of water that is delivered through the system per hour. It is important to select a flow rate that is appropriate for your field and your plants’ water needs.

To use the calculator, simply enter the field size, emitter spacing, and flow rate into the corresponding input fields and click the “Calculate” button.

The calculator will then use these inputs to calculate the number of emitters needed and the total length of drip line required, and display the results in the “Number of emitters needed” and “Total length of drip line needed” fields, respectively.

## How is the output calculated?

The “Number of emitters needed” and “Total length of dripline needed” outputs of the dripline calculator are calculated using the following formulas:

1. Number of emitters needed = field size / (emitter spacing * emitter spacing) This formula calculates the number of emitters needed by dividing the field size by the area covered by each emitter (emitter spacing * emitter spacing).
2. Total length of dripline needed = number of emitters * flow rate / (60 * 6) This formula calculates the total length of dripline needed by multiplying the number of emitters by the flow rate (in gallons per hour) and dividing the result by the number of seconds in an hour (60) and the number of seconds in a minute (6).

These formulas use the field size, emitter spacing, and flow rate inputs entered by the user to calculate the number of emitters needed and the total length of dripline required for the user’s specific situation.

## Dripline FAQs

### 1. How do you calculate dripline?

To calculate dripline, you need to determine the size of the area you want to irrigate, the emitter spacing, and the flow rate of your irrigation system. Total length of dripline needed = number of emitters * flow rate / (60 * 6)

### 2. How many emitters are on a 12-inch drip line?

The number of emitters on a 12 inch drip line will depend on the size of the area you want to irrigate and the flow rate of your irrigation system. You can use the formulas mentioned above to calculate the number of emitters needed for your specific situation.

### 3. How many gallons per hour does a drip line put out?

The flow rate of a drip line, in gallons per hour, will depend on the size of the emitters and the pressure of the water supply. You can refer to the manufacturer’s specifications or use a flow rate calculator to determine the flow rate of your drip line.

### 4. How far can you run Dripline?

The maximum distance you can run dripline will depend on the flow rate and the pressure of your water supply. In general, it is recommended to keep the total length of the dripline under 1000 feet to ensure sufficient pressure and flow rate.

### 5. What is the easiest way to calculate drip rate?

The easiest way to calculate drip rate is to use a drip rate calculator or a drip rate formula. To calculate drip rate using a formula, you can use the following:
Drip rate (gph) = flow rate (gpm) / 60 / emitter spacing (emitters per foot)

### 6. How do you calculate dripper discharge?

To calculate dripper discharge, you can use the following formula:
Dripper discharge (gph) = flow rate (gpm) / 60 / number of emitters

### 7. How much drip tape per acre?

The amount of drip tape needed per acre will depend on the spacing of the emitters and the flow rate of your irrigation system.

### 8. Should drip emitters be buried?

In general, it is not necessary to bury drip emitters. They can be left above ground or installed at a shallow depth, as long as they are protected from physical damage and are not exposed to direct sunlight.

### 9. How many drips equal a gallon?

The number of drips that equal a gallon will depend on the flow rate of the emitters. For example, if the flow rate of an emitter is 0.5 gallons per hour, it will take 2 hours for the emitter to deliver 1 gallon of water.

### 10. How often should I water with drip irrigation?

The frequency of watering with drip irrigation will depend on the water needs of your plants, the climate, and the soil type. In general, it is recommended to water deeply and infrequently to encourage deep root growth and conserve water.

### 11. Do you need a pressure regulator for a Dripline?

A pressure regulator may be needed for a dripline if the pressure of the water supply is too high or too low for the system to operate effectively. A pressure regulator helps to maintain a consistent flow rate and prevents damage to the dripline and emitters.

### 12. Should I run drip irrigation every day?

It is generally not necessary to run drip irrigation every day. Watering deeply and infrequently is typically more effective for promoting deep root growth and conserving water.

### 13. How many drip heads per zone?

The number of drip heads per zone will depend on the size of the zone and the flow rate of the drip heads. It is important to consider the water needs of your plants and the capacity of your irrigation system when determining the number of drip heads per zone.

### 14. Should drip tape face up or down?

Drip tape should generally be placed with the emitters facing down, towards the plants, to ensure that the water is delivered directly to the root zone.
