What does the specific weight of water measure?

• A. Weight per volume
• B. Density
• C. Pressure unit
• D. Flow rate

Answer: (A)

The specific weight of water measures the weight per unit volume of the water. It is a crucial property in fluid mechanics and civil engineering, often represented as the weight of water divided by its volume. This measurement is important for understanding buoyancy, designing water-related structures like dams and levees, and calculating pressures exerted by water at various depths. Specific weight is mathematically defined as the product of the density and the acceleration due to gravity. This means that knowing the specific weight allows engineers to relate the weight of water directly to its volume, which is essential for calculations in various civil engineering applications. While density relates to mass per volume, specific weight incorporates the gravitational force acting on that mass, making it a more relevant metric in many engineering contexts, especially when dealing with submerged or buoyant conditions. Understanding specific weight is critical when evaluating how fluids behave under different conditions, which helps engineers make informed decisions when designing systems that involve both static and dynamic fluid environments.
