F = 735N
Answer:
Explanation:
The speed of the water in the large section of the pipe is not stated
so i will assume 36m/s
(if its not the said speed, input the figure of your speed and you get it right)
Continuity equation is applicable for ideal, incompressible liquids
Q the flux of water that is Av with A the cross section area and v the velocity,
so,


the diameter decreases 86% so


Thus, speed in smaller section is 48.6 m/s
There is no suitable description on the list you provided.
