**Introduction**

The Rod Load Calculator is a valuable tool for those involved in rod pump system analysis and design. It allows you to determine the rod load in pounds-force (lb-f) based on essential parameters such as bore diameter, rod diameter, suction pressure, and discharge pressure. Understanding the rod load is crucial for ensuring the proper functioning and longevity of rod pumps in oil and gas production. This guide will show you how to use the calculator effectively, provide the formula behind it, walk through an example calculation, and address common questions about rod loads.

**How to Use**

Using the Rod Load Calculator is straightforward. Follow these steps:

- Input the bore diameter (inches).
- Input the rod diameter (inches).
- Input the suction pressure (PSI).
- Input the discharge pressure (PSI).
- Click the “Calculate” button to find the rod load (lb-f).

**Formula**

The formula used in the Rod Load Calculator is as follows: CRL = B^2 * P2 – (B^2 – R^2) * P1

Where:

- CRL represents the Rod Load (lb-f)
- B is the bore diameter (inches)
- R is the rod diameter (inches)
- P1 is the suction pressure (PSI)
- P2 is the discharge pressure (PSI)

**Example**

Let’s work through an example:

- Bore diameter (B) = 4 inches
- Rod diameter (R) = 1 inch
- Suction pressure (P1) = 50 PSI
- Discharge pressure (P2) = 200 PSI

Using the formula, we can calculate the Rod Load (CRL): CRL = 4^2 * 200 – (4^2 – 1^2) * 50 CRL = 3200 lb-f

So, the rod load is 3200 pounds-force.

**FAQs**
