According to equation of continuity A2v1= A2v2 = constant, the constant is equal to
Correct answer: A. flow rate
- A. flow rate
- B. volume of fluid
- C. mass of fluid
- D. density of fluid
Explanation
Av= A(s/t)=V/t ∵A=area , v=velocity, V=volume, t=timeThe V/t is the rate of change of volume and is also called as flow rate

About Fluid Dynamics
Fluid flow is described through speed, pressure and density, including steady flow and the equation of continuity for conserving mass. Bernoulli's equation relates pressure, speed and height, while fluid drag and terminal velocity explain why a falling object eventually moves at constant speed when drag balances its weight.
