Firefighter Aptitude Test Tuesdays – Water Tanks
Every Tuesday I post a common question you might encounter during your firefighter aptitude test. This week we will be covering water tanks.
For more questions, have a look at the Firefighter Practice Tests – Premium Pack. They offer over 99 practice tests and over 1500 questions.
The figure below shows water tanks I and II. The tanks have different shapes. If both tanks are of the same capacity, which of them would deliver higher water pressures at elevation?
1) Both tanks would deliver the same pressure
2) Tank II
3) Tank I
4) Cannot be determined
The pressure of a water container is proportional to its water height.
The tank with the higher water level will deliver higher pressure.
Water tank I has the higher water level.
Therefore, water tank I will deliver water with higher pressure.
