Question
A swimming pool has dimensions 34.0 m 9.0 m and a flat bottom. The pool is filled to a depth of 2.30 m with fresh water. (Enter only the answers in the input boxes separately given.)
(a) What is the force exerted by the water on the bottom?
1. (Enter in box 1) N down
(b) What is the force exerted by the water on each end? (The ends are 9.0 m.)
2. (Enter in box 2) N outward
(c) What is the force exerted by the water on each side? (The sides are 34.0 m.)
3. (Enter in box 3) N outward
4. ( Enter in the box) Pa
(e) What force is exerted by the water on the window of an underwater vehicle at this depth if the window is circular and has a diameter of 34.8cm?
5. (Enter in the box) N
Explanation / Answer
as per guidelines i can only solve 3 parts for you
given are
34.0 m 9.0 m-dimensions
Area=306m^2
h=2.30 m
pressure at the bottom wil be=pgh(p=1000)
=1000*9.8*2.30
=22540Pa
Fb=PbA
=22540*306
=6897240
Fb=6.8*10^6N--answer to a
b)P=pg
=1000*9.8
=9.8*10^3
F=PA
=9.8*10^3*(9*2.30)
=202.86*10^3
F=2.02*10^5N
c)Force exterted on each side will be
P=same as calculated in oart b
P=9.8*10^3
F=9.8*10^3*(34*2.30)
=766,36*10^3
F=7.6*10^5N
