Maybe the streamline formation will be as shown in the figure. Consider the center most straight streamline 1 → 2 where 1 is a point far away from the submarine where the fluid particle is actually at absolute rest but in another frame of reference i.e. with respect to the submarine it is moving with a speed of 5 m/sec. ∴ V1 = 5.0 m/sec.
V2 = 0
and as fluid is at absolute rest at 1, p1 = ρgh where h = 50 m Let us apply Bernoulli’s equation between 1 and 2.
p2 = 518090 Pa or 518.09 kPa
Note: Even though flow is unsteady in actual but by changing the frame of reference and writing motion relative to submarine flow becomes steady and Bernoulli’s equation is applicable.
