Answer:
Person B
Explanation:
Person B will hear the frequency that is lower than the B- flat.
density of water = 
velocity of flow = 
radius of pipe = 
Height of second floor = 
Now we can use here Bernuoli's Equation to find the speed of water flow at second floor
Now in order to find the radius of pipe we can use equation of continuity
So radius of pipe at second floor is 0.034 meter
