Self-registering thermometers
are used for temperature or depth profile. It registers the maximum and minimum
temperature of the substance occurring in the interval of time between two
consecutive settings of the instrument.
Answer:
Explanation:
= Initial diameter = 4 cm
= Initial velocity = 1 m/s
= Final diameter = 7.8 m
= Final velocity
= Area = 
From the continuity equation we get
The speed of water at the second floor is .
I took the test and this is the answer key showing I got it right..
Hope this helps!
