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

Alignment methods are techniques used to ensure proper positioning and orientation of mechanical components.

• Common alignment methods include laser alignment, dial indicator alignment, and straight edge alignment.

• Laser alignment uses a laser beam to measure and adjust the alignment of components.

• Dial indicator alignment uses a dial gauge to measure the alignment of components.

• Straight edge alignment involves using a str...read more

Pressure classes are categories used to classify the pressure rating of piping components.

• Pressure classes are used to indicate the maximum allowable working pressure for piping components.

• Common pressure classes include 150, 300, 600, 900, 1500, and 2500.

• Each pressure class corresponds to a specific pressure rating in pounds per square inch (psi).

• Pressure classes are important for selecting the right components for a
