The relation that keeps mass constant as an incompressible fluid flows through a changing pipe is the:
AEquation of conversion
BEquation of conduction
CEquation of continuity
DEquation of condition
Answer & Solution
Correct answer: C. Equation of continuity
1. What flows in must flow out.
2. A narrower section must carry faster flow.
3. That relation is the equation of continuity.
