Pipes and Cisterns questions are a type of arithmetic math question that involves pipes filling or emptying a cistern. The goal is to determine the time it takes to fill or empty the cistern, or the amount of water that is filled or emptied in a certain amount of time.
Formulas for solving Pipes and Cisterns Problems
The formulas for solving Pipes and Cisterns problems are:
- Part filled in 1 hour: (1 / filling time) - (1 / emptying time)
- Time to fill a cistern: (1 / filling rate) - (1 / emptying rate)
- Amount of water filled in a certain time: (partly filled in 1 hour) * (time)
For example, let's say a cistern can be filled by two pipes A and B in 6 hours and 8 hours respectively. If both pipes are opened together, the cistern will be filled in 24/(1/6 + 1/8) = 24/7 hours. The formula for solving this problem is:
- Part filled in 1 hour = (1 / 6) - (1 / 8) = 7/48
- Time to fill a cistern = (1 / part filled in 1 hour) = 48/7 hours
Pipes and Cisterns problems can be challenging, but they can be solved using the formulas above. With a little practice, you'll be able to solve these types of problems quickly and easily.
Tips for solving Pipes and Cisterns Problem
Here are some tips for solving Pipes and Cisterns problems:
- Make sure you understand the difference between filling time and emptying time.
- Use the formulas above to solve the problem.
- Check your answer to make sure it makes sense.
With a little practice, you'll be able to solve Pipes and Cisterns problems like a pro!
Here are some additional examples of Pipes and Cisterns questions:
- A cistern can be filled by pipe A in 6 hours and by pipe B in 8 hours. If both pipes are opened together, how long will it take to fill the cistern?
- A cistern can be emptied by pipe C in 12 hours. If pipe A and pipe B are opened together, filling the cistern in 6 hours. How long will it take to empty the cistern if pipes A, B, and C are opened together?
- A cistern is filled with water in 10 hours. A leak develops in the bottom of the cistern and it takes 12 hours to fill the cistern. How long will it take the leak to empty the full cistern?
