1atm = 1.853454Pa

=======================

flow velocity1.7 m/s

pressure = 1.85atm

By continuity equation:

v2 = (A1v1) / A2 = (d1/d2)v1 = (4.2/2.6)* 0.65 = 1.7 m/s

By Bernoullis Equation:

P1 gh1 (v1)= P2 gh2 (v2)

[v1 -v2] /2 = (P2-P1)/ g(h2 -h1)

(0.65- 1.7)/2 = (P2-P1)/ 1000 9.8*20

-1.23375= (P2-P1)/ 1000 196

(P2-P1) = 197233.75 Pa

P2 = P1-197233.75, P1 = 3.8atm = 385035 Pa

P2 = 385035-197233.75 = 187801.25 Pa ( gauge pressure)

1atm = 1.853454Pa
