The specific weight of a fluid is defined as its:
Correct answer: A. Weight per unit volume
- A. Weight per unit volume
- B. Mass per unit volume
- C. Volume per unit mass
- D. Weight per unit area
Explanation
Specific weight is the gravitational force or weight contained in a unit volume of fluid. It equals density multiplied by gravitational acceleration, whereas mass per unit volume is density.

About Hydraulics and Water Resources
Hydraulics studies fluid properties, pressure, buoyancy, continuity, Bernoulli's equation, momentum, pipe flow, open-channel flow and hydraulic machines. Water resources extends these principles to pumps, turbines, reservoirs, irrigation, floods and hydrology, while distinguishing laminar from turbulent flow and uniform from gradually varied channel flow.
