The sound absorption coefficient for metals is a measure of how effectively metal surfaces absorb sound energy rather than reflecting it. This coefficient, denoted typically by αα, ranges from 0 (no absorption, total reflection) to 1 (total absorption). For metals, the sound absorption coefficient is generally very low because of their dense, rigid, and reflective surface properties, but … Read more
Sound absorption is crucial in creating comfortable, acoustically balanced interiors. Whether in homes, offices, studios, or classrooms, controlling how sound behaves with walls significantly impacts noise levels, speech clarity, and overall acoustic comfort. At the core of measuring a material’s ability to absorb sound is the sound absorption coefficient—a fundamental property determining how much sound energy … Read more
The speed of sound in air at sea level is approximately 343 meters per second (m/s) or about 1,235 kilometers per hour (km/h, 767 mph) at a temperature of 20°C (68°F). This is the generally accepted standard value used in many applications such as physics and engineering. Speed of Sound Calculator (Air at Sea Level) Enter Temperature (°C): Calculate … Read more

Flow rate per hour typically refers to the volume of fluid passing through a given cross-sectional area of a pipe, channel, or system within one hour. It is a volumetric measurement commonly expressed in units like cubic meters per hour (m³/hr), liters per hour (L/hr), or gallons per hour (GPH). The flow rate measures how … Read more
Meters per minute (m/min) is a unit of speed that measures how many meters an object travels in one minute. It is especially useful for representing moderate speeds in various industries and applications where travel or flow speeds are relatively slow or need precise control. This blog post explores everything you need to know about … Read more
Understanding the relationship between fluid velocity and flow rate is fundamental in hydraulic engineering, plumbing design, and various industrial applications. The conversion from FPS (Feet Per Second) to GPM (Gallons Per Minute) is a critical calculation that bridges the gap between velocity measurements and volumetric flow requirements. This comprehensive guide will walk you through the … Read more
Centrifugal pumps are among the most widely used types of pumps across industries — from water treatment and irrigation to oil refining and chemical processing. A key parameter that determines their effectiveness and application suitability is the flow rate. Understanding what centrifugal pump flow rate is, how it’s calculated, and how it affects pump performance … Read more
Whether you’re growing crops on a large field, maintaining a greenhouse, or keeping your garden lush, one factor is critical: water flow. The flow rate of your water pump is a foundational element in irrigation planning. It determines how efficiently and effectively your plants receive water — and how much energy and time you waste … Read more
