# CC/REV to GPM Calculator

## About CC/REV to GPM Calculator (Formula)

Converting CC/REV to GPM is essential in hydraulics and fluid dynamics to understand the flow rate of pumps and other machinery. Knowing the flow rate in gallons per minute helps in designing and optimizing fluid systems. The CC/REV to GPM Calculator provides an easy way to make this conversion, allowing you to quickly determine the fluid flow rate based on the pump’s specifications.

### Formula

The formula for converting CC/REV to GPM is:

• GPM = (CC/REV / 3785) * RPM

Where:

• GPM = Gallons Per Minute
• CC/REV = Cubic Centimeters per Revolution (the volume of fluid moved per pump revolution)
• RPM = Revolutions Per Minute (the speed at which the pump operates)
• 3785 = Conversion factor from cubic centimeters to gallons

### How to Use

To use the CC/REV to GPM Calculator:

1. Determine the CC/REV, which is the volume of fluid the pump moves per revolution, measured in cubic centimeters.
2. Identify the RPM, which is the speed at which the pump operates, measured in revolutions per minute.
3. Use the formula: GPM = (CC/REV / 3785) * RPM.
4. The result will give you the flow rate in gallons per minute.

### Example

Let’s calculate the GPM for a pump with:

• CC/REV = 150
• RPM = 1800

Using the formula:

1. GPM = (150 / 3785) * 1800
2. GPM = 0.0396 * 1800
3. GPM ≈ 71.28

Therefore, the flow rate of the pump is approximately 71.28 gallons per minute.

### FAQs

1. What does CC/REV mean?
• CC/REV stands for Cubic Centimeters per Revolution, which indicates the volume of fluid a pump moves with each revolution.
2. Why convert CC/REV to GPM?
• Converting CC/REV to GPM helps in understanding the pump’s flow rate in more practical terms, especially for systems that use gallons per minute as a standard measurement.
3. What is RPM in the formula?
• RPM stands for Revolutions Per Minute, which is the speed at which the pump operates, affecting the flow rate.
4. Why is the number 3785 used in the formula?
• The number 3785 is the approximate number of cubic centimeters in a gallon, used here to convert the flow rate from cubic centimeters to gallons.
5. Can I use this calculator for any type of pump?
• Yes, this calculator can be used for any pump that provides CC/REV and RPM specifications, including hydraulic and fluid pumps.
6. What units should I use for the input values?
• Use cubic centimeters (CC) for the volume per revolution and revolutions per minute (RPM) for the speed.
7. How does increasing RPM affect GPM?
• Increasing RPM increases the flow rate (GPM) since the pump moves more fluid per unit of time.
8. Is the formula applicable for both liquids and gases?
• This formula is typically used for liquids. For gases, other factors like compressibility need to be considered.
9. How does the pump’s efficiency affect the GPM?
• The formula assumes ideal conditions. In practice, pump efficiency and factors like leakage and slippage may reduce the actual GPM.
10. Can I use this formula for pumps with variable displacement?
• For variable displacement pumps, the CC/REV can change. You need to use the current displacement value for an accurate GPM calculation.
11. How do I measure the CC/REV for my pump?
• CC/REV is usually provided in the pump’s specifications. If not, it can be determined by measuring the volume of fluid moved in one revolution.
12. What if my pump’s specifications are in liters per revolution?
• Convert liters to cubic centimeters (1 liter = 1000 cubic centimeters) before using the formula.
13. Does this calculator account for losses in the system?
• No, this calculation assumes ideal conditions and does not account for losses like friction or leakage in the system.
14. What is a typical GPM for hydraulic pumps?
• Hydraulic pumps can have a wide range of GPM values, typically from 0.5 to 30 GPM or more, depending on the application.
15. How can I increase the GPM of my pump?
• Increase the pump’s RPM or use a pump with a higher CC/REV. However, ensure the system can handle the increased flow rate.
16. What is the significance of GPM in hydraulic systems?
• GPM indicates the flow rate of fluid through the system, affecting the speed and performance of hydraulic actuators.
17. Can the GPM change with the type of fluid used?
• Yes, the viscosity and density of the fluid can affect the actual GPM due to changes in flow characteristics.
18. Is GPM the same as flow rate?
• Yes, GPM is a measure of flow rate, specifically in gallons per minute.
19. Does the size of the pump affect the GPM?
• Yes, larger pumps typically have higher CC/REV values, resulting in a higher GPM at the same RPM.
20. What safety precautions should be taken when adjusting RPM for higher GPM?
• Ensure the system’s components can handle the increased flow rate and pressure to avoid damage or failure.

### Conclusion

The CC/REV to GPM Calculator is a valuable tool for engineers and technicians working with hydraulic systems and fluid pumps. By converting the pump’s specifications into a flow rate, you can better understand and optimize your system’s performance. Whether you’re designing a new system or troubleshooting an existing one, this calculator provides a quick and accurate way to determine the flow rate in gallons per minute.
