Oil enters a 100-mm-diameter pipe steadily with a velocity of 5 m/s. The gage pressure in the pipe at A and B is 80 kPa. The den
sity of the oil is 900 kg/m3. Neglect gravitational effects. Determine the reaction force exerted on the elbow by the couplings at A and B. Please clearly define the coordinate system and the control volume.

Answer:
a = 2 [m/s²]
Explanation:
To be able to solve this problem we must make it clear that the starting point when the time is equal to zero, the velocity is 5 [m/s] and when three seconds have passed the velocity is 11 [m/s], this point is the final point or the final velocity.
We can use the following equation.
where:
Vf = final velocity = 11 [m/s]
Vo = initial velocity = 5 [m/s]
a = acceleration [m/s²]
t = time = 3 [s]
