Pipe and Cistern Formula
Given below are a few important formulas which shall help you solve the pipes and cistern based questions quicker and more efficiently:
- If x hours are required to fill up a tank, then part filled in 1 hr =1/x
- Net work done = (Sum of work done by Inlets) – (Sum of work done by Outlets)
- If y hours are required to empty the tank, then part emptied in 1 hour = 1/y
- If a pipe can fill a tank in x hours and can empty the same tank in y hours. When both the pipes are opened at the same time,. Then the net part of the tank filled in 1 hr = {(xy) / (y-x)}, provided y>x
- If a pipe can fill a tank in x hours and can empty the same tank in y hours. When both the pipes are opened at the same time, then the net part of the tank filled in 1 hr = {(xy) / (x-y)}, provided x>y
- One inlet can fill the tank in x hr and the other inlet can fill the same tank in y hrs, if both the inlets are opened at the same time, the time taken to fill the whole tank = {(xy) / (y+x)}
- If two pipes take x and y hours respectively to fill a tank of water and a third pipe is opened which takes z hours to empty the tank, then the time taken to fill the tank = {1 / (1/x)+(1/y)+(1/z)} and the net part of the tank filled in 1 hr = (1/x)+(1/y)-(1/z)
Just memorising the above-mentioned formulas may not be sufficient,. Candidates need to solve more and more sample questions based on the same in order to excel in this topic.
