Becoming a doctor requires more training than most other jobs. It usually takes at least 11 years to become a doctor: 4 years of college, 4 years of medical school, and 3 years working in a hospital. For some specialties, doctors may have to work in a hospital for up to 8 years before they are fully trained.
This requires large volumes of water - between 500 and 1000 gallons per minute - depending on the diameter of the water main. This is why you may see us âflushingâ fire hydrants and letting the water run down the street. This is a standard procedure and the water is dechlorinated to protect the environment.
The user attaches a hose to the fire hydrant, then opens a valve on the hydrant to provide a powerful flow of water, on the order of 350 kPa (50 lbf/inÂ²) (this pressure varies according to region and depends on various factors including the size and location of the attached water main).
