Inflow rate of volume of the liquid = Outflow rate of volume of the liquid. πR²V = πr²(v) => πR² = πr² => nr².

1. πR²V = πr²v
2. πR² = πr²
3. nr²
4. None of the above

Correct answer: πR²V = πr²v

Solution

The equation πR²V = πr²v represents the continuity equation, which states that the inflow rate of volume equals the outflow rate of volume for an incompressible fluid. This matches the given condition.
