There is a lot of pressure. Yes, it can hurt.
If I remember correctly, the pressure from a hydrant is around 45 PSI. The pumper truck is connected to the hydrant. The pumper has a pump, hense the name, that increases the pressure to around 75-100 PSI, as I remember. That might be way off.
In any event, it is a lot of pressure. Especially since there is a tremendous amount of volume of water.
They sometimes use a fire hose in riot control. It can knock people down, literally.
If a fire hose gets loose and is turned on, the nossle whips around, out of control. It can break a leg, or cause even worse damage or injury.
In practice drills, there is a person with a cuttoff valve ready to instantly cut the water flow if the hose gets dropped.

It depends on how high the fire truck pump operator sets the pressure. It would be a minimum of 80 psi and can go a LOT higher depending on the lift needed and size of hose. Water is usually pumped from the hydrant through a pump in the truck.

The pressure you use to attack a fire can range anywhere from 100 psi up to 250 psi. the majority of attack lines operate around 100-150 psi and yes they can knock you down and yes they do hurt, especially if hit in sensitive areas. we try and not to hit people with water streams if possible, but sometimes it happens and I can tell you from experience that it does hurt. we take the hydrant pressure (50-120 psi) and flow it through a pump to boost the pressure not the volume up to a good working pressure 100-250 depending on the needs required then out through the nozzle. hope this answers your question!

depends. If it pressure from a water mains then that pressure would differ from time to time. if is being pumped by the power of the fire engine then I do not know what power that would be . I dont think it would be a good idea to stand in front of one being used.

It can hurt, and it can kill. If you get hit, you could be washed up for life.
