2. Can you explain the concept of efficiency in relation to pipes and cisterns?
Ans. Efficiency in pipes and cisterns refers to the rate at which a pipe or cistern can fill or empty a tank. It is often calculated as the ratio of the work done by the pipe or cistern to the work it could have done under ideal conditions.
3. How do you find the rate of filling/emptying for a pipe or cistern?
Ans. The rate of filling/emptying for a pipe or cistern can be calculated by dividing the total work done by the pipe/cistern by the time taken to fill/empty the cistern.
4. What is the concept of a leak in a cistern and how does it affect the filling time?
Ans. A leak in a cistern refers to a small hole through which water escapes. When there is a leak in a cistern, it reduces the effective filling rate, thereby increasing the time taken to fill the cistern.
5. How do you find the individual rates of two pipes working together to fill a cistern?
