Good day sir, in the video the loss coefficient you used in four 90° elbows (threaded) is 1.5 and casually the present book suggested that the loss coefficient for 90° elbow (threaded) is 0.9. So far as I used what the book suggested, my result for getting the pressure 1 is 3266.54 lb.f/ft² or approximately 22.68 lb.f/in² which is smaller from your result.

Is it known that at state 2 its free jet or is it an assumptions? If it's an assumption then I really can't tell if it is or not free jet at state 1
Woooowwwww😮😮, cool explanation
