FAQs on Pipes & Cisterns Video Lecture - Quantitative Aptitude (Quant) - CAT

1. What are some common applications of pipes and cisterns in daily life?
Ans. Pipes and cisterns are commonly used in various daily life activities such as plumbing systems in buildings, water supply networks, irrigation systems, and drainage systems.
2. How can one calculate the time taken to fill a cistern when multiple pipes are involved?
Ans. To calculate the time taken to fill a cistern with multiple pipes, we add the rates of each pipe and then divide the volume of the cistern by the combined rate of all the pipes.
3. How can one determine the capacity of a cistern using pipe filling and emptying methods?
Ans. To determine the capacity of a cistern using pipe filling and emptying methods, one can calculate the rate of filling and emptying separately and then find the difference between the two rates. The capacity of the cistern is then given by the ratio of the volume of the pipe filling the cistern to the difference in rates.
4. What are the different types of problems that can be solved using the concept of pipes and cisterns?
Ans. The concept of pipes and cisterns is used to solve various types of problems such as finding the time taken to fill or empty a cistern, determining the capacity of a cistern, calculating the rate at which a pipe can fill or empty a cistern, and finding the time taken to fill a cistern when multiple pipes are involved.
5. How can one calculate the time taken to empty a cistern when a pipe is involved in both filling and emptying?
Ans. When a pipe is involved in both filling and emptying a cistern, we calculate the individual rates of filling and emptying. The net rate of emptying is then given by the difference between the rate of emptying and the rate of filling. The time taken to empty the cistern can be calculated by dividing the capacity of the cistern by the net rate of emptying.
