I get the feeling this is your homework ;)
empty rate per minute = 1/20 bath
fill rate per minute = 1/12 bath
find t= minutes to when bath is full, 1/t bath (combined empty and fill rate)
so 1/12 - 1/20 = 1/t
solve that for t and you have your answer in minutes ;)
The time it takes to drain a bathtub typically ranges from 5 to 15 minutes, depending on factors such as the size of the drain opening and the water level. Factors like clogs or the type of plumbing can also influence drainage speed. If a bathtub takes significantly longer to drain, it may indicate a blockage that needs to be addressed.
you should drain it using your mouth
Draining a hot water heater typically takes about 30 minutes to an hour, depending on the tank size and the flow rate of the water being drained. To expedite the process, ensure the water heater is turned off and the cold water supply is shut off before opening the drain valve. The actual draining time will vary based on the amount of sediment buildup in the tank and the length of the hose used to direct the water. Always take necessary safety precautions when working with hot water.
A tub drain works by allowing water to flow out of the bathtub through a pipe connected to the drain. When the stopper is lifted or turned, water is able to pass through the drain and into the plumbing system, ultimately leading the water away from the tub and out of the house.
A bathtub drain works by using a system of pipes and a stopper to allow water to flow out of the tub. When the stopper is lifted or turned, it creates a pathway for the water to drain through the pipes and out of the tub, preventing the water from overflowing.
There should be no reason the toilet would overflow. The water being turned off should have no effect on it. As long as the drain is clear even if the shut off valve in the tank didn't work, the water will just go down the drain.
To drain the water that is in the pipe or spout..
A bathtub drain works by using a system of pipes and a plug mechanism to allow water to flow out of the tub. When the plug is lifted or turned, it opens a pathway for the water to drain through the pipes and out of the tub, preventing the water from overflowing.
If your drain line becomes clogged, a mixture of hot water, vinegar, and baking soda can be used to clear it. After letting the mixture lie in the drain for 10-15 minutes, pour hot water down the drain first, then baking soda, vinegar, then more hot water.
It typically takes a few minutes to an hour for water to start flowing from a well after it has been turned on following the winter. This time can vary depending on the depth of the well, the distance to the water table, and the condition of the well system.
It would take 4.5 minutes for a kettle to boil 1.5 liters of water since it takes 3 minutes to boil 1 liter.
The sink only drains when the garbage disposal is turned on because the garbage disposal helps to break down and remove food particles that may be blocking the drain, allowing water to flow freely.
