Gpm for water supply pump can be calculated by dividing the flow rate in gallons by the time in minutes.

• Calculate the flow rate in gallons per minute (GPM)

• Determine the time in minutes over which the flow rate is measured

• Divide the flow rate by the time to get the GPM value

Heat exchangers are devices used to transfer heat between two or more fluids, ensuring efficient heat transfer and temperature control.

• Transfer heat between fluids

• Maintain temperature control

• Increase energy efficiency

• Commonly used in HVAC systems, refrigeration units, and chemical processing plants
