Lb/hr to Gpm Calculator



 

About Lb/hr to Gpm Calculator (Formula)

In various industries, measuring the flow rate of liquids is crucial for ensuring efficiency and safety. One common conversion is from pounds per hour (lb/hr) to gallons per minute (GPM). This conversion is particularly important in fields such as food and beverage processing, chemical manufacturing, and pharmaceuticals. The lb/hr to GPM calculator simplifies this process, allowing for quick and accurate conversions that facilitate operations and regulatory compliance.

Formula

The formula to convert lb/hr to GPM is: GPM = LB/hr / D / 60, where D represents the density of the fluid in pounds per gallon.

How to Use

To use the lb/hr to GPM calculator, follow these simple steps:

  1. Identify the Density: Determine the density (D) of the liquid you are converting. This value is usually found in tables or material safety data sheets.
  2. Input lb/hr: Enter the flow rate in pounds per hour (lb/hr) into the calculator.
  3. Calculate: The calculator will apply the formula and provide the flow rate in gallons per minute (GPM).

Example

Suppose you have a liquid with a density of 8.34 lbs/gallon (typical for water) and a flow rate of 200 lb/hr. To find the flow rate in GPM:

  1. Identify D: 8.34 lbs/gallon
  2. Input lb/hr: 200 lb/hr
  3. Apply the formula: GPM = 200 / 8.34 / 60 = 0.399 GPM

So, the flow rate is approximately 0.399 GPM.
