Did you know?

The “pound per hour” (lb/h) is a unit of flow rate often used in engineering and manufacturing to describe the mass of a substance, such as steam or fuel, moving through a system over time. While commonly associated with industrial processes, this unit plays a crucial role in everyday appliances, like HVAC systems, to ensure optimal performance and energy efficiency by precisely managing the flow of refrigerant or air.

Historically, the pound per hour measurement gained prominence during the Industrial Revolution when steam engines were vital for transportation and industry. By calculating steam flow in pounds per hour, engineers of the time could effectively control machinery, optimize fuel use, and enhance productivity—a legacy that continues to influence modern engineering practices.
