Pipes and Cisterns Questions and Answers
Pipes and Cisterns Aptitude Questions
On this page we will be discussing about Pipes And Cistern Questions that are generally asked in placement Exams. Pipes and Cistern is a common topic asked in various companies exams. Two basic terminologies in Pipes and Cistern Topic are:
Inlet
A pipe which is used to fill water in a tank. This is considered as Positive work done
Outlet
A pipe which is used to empty the tank filled with water. This is considered as negative work done.
Rules for Pipes and Cisterns
- Inlet is referred to as the pipe which is supposed to fill the tank.
- A pipe that is meant to empty the tank is called as outlet.
- When a pipe works for x hours for filling up the cistern, then 1/x portion of the cistern will be completed in 1 hour.
- When a pipe works for y hours to empty the cistern, then the portion of the cistern emptied in 1 hour is equals to
= \frac{1}{y} - Pipe A might fill a cistern n times as quickly as another pipe B. This states that if slower pipe B works for x min to fill the empty tank,
then quicker pipe A works for x/n min to fill up the empty cistern. If they work collaboratively, then the portion of the cistern which is loaded up in 1 hour is
= \frac{n+1}{x} - In some scenarios the efficiency of the pipes would have been given such as in percentage, to find the actual rate multiply the efficiency percentage with rate.
- Be very careful when using Units make sure all the units are same, or else answer might get wrong.
Formulas to keep in mind.
Time, Rate, and Volume Relationship:
Time = Volume / Rate
Rate = Volume / Time
Volume = Rate × Time
