If you take a narrow and a broad pipe and make same amount of water pass through I.e same flow rate .

And stand at front of both of them

Water from Narrow one hurts more!

Why although same amount water of water coming out in unit time?

Does it due to water molecule velocity in narrow pipe is more(as we know if they have same flow rate, if you want diagram please let me know)?

Why doesn't broad one hurts? How high velocity make us feel high pressure?
