This can happen because speed has nothing to do with something’s top speed. Acceleration is how quickly something can reach its top speed. The top speed of something is not determined by the rate it accelerates.
Answer:
The velocity is 
The pressure is 
Explanation:
From the question we are told that
The speed at which water is travelling through is 
The pressure is 
The diameter of the new pipe is
Where D is the diameter of first pipe
According to the principal of continuity we have that
Now
is the area of the first pipe which is mathematically represented as

and
is the area of the second pipe which is mathematically represented as

Recall
![A_2 = \pi \frac{[ D^2]}{4 *4}](https://tex.z-dn.net/?f=A_2%20%3D%20%5Cpi%20%20%5Cfrac%7B%5B%20D%5E2%5D%7D%7B4%20%2A4%7D)

So 
substituting value

According to Bernoulli's equation we have that

substituting values


I believe it's Seismographs, Tiltmeters, and Correlation Spectometers.
Hopefully I helped ^~^
