1.Inlet :
A pipe connected with a tank or a cistern or a reservoir, that fills it, is known as an inlet.
Outlet :
A pipe connected with a tank or cistern or reservoir, emptying it, is known as an outlet.
2. If a pipe can fill a tank in x hours, then :
part filled in 1 hour = 1 / x.
3. a) If a pipe can empty a tank in y hours, then :
part emptied in 1 hour = 1 / y.
b) If a pipe can fill a tank in x hours and another pipe can empty the full tank in y hours (where

b) If a pipe can fill a tank in x hours and another pipe can empty the full tank in y hours (where
y > x), then on opening both the pipes,
then the net part filled in 1 hour = (1 / x - 1 / y).
c) If a pipe can fill a tank in x hours and another pipe can empty the full tank in y hours (where
then the net part filled in 1 hour = (1 / x - 1 / y).

y > x), then on opening both the pipes,
then the net part emptied in 1 hour = (1 / y - 1 / x).
then the net part emptied in 1 hour = (1 / y - 1 / x).
