What is the density of water at a temperature of 20℃?

The density of water at a temperature of 20℃ is approximately 998.2 kg/m³. This value is widely accepted in scientific literature and is relevant for many applications, including wastewater treatment processes, where precise density values can be crucial for calculations involving fluid dynamics, chemical dosing, and other operational parameters.

At 20℃, the behavior of water, including its density, can be influenced by factors such as temperature and impurities. However, the commonly referenced value of 998.2 kg/m³ serves as a standard for clean water at room temperature. This measurement is important for professionals in the field of wastewater treatment, as accurate density values can help in designing and operating treatment systems effectively.

Understanding this density helps ensure that calculations involving buoyancy, sedimentation, and liquid volume conversions are accurate, which is essential for maintaining operational efficiency and compliance with regulatory standards.
