Question

Dimensions of a swimming pool are 34.0 m by

8.5 m and its uniform depth is 2.9 m . The atmospheric pressure is 1.013×105N/m2.

Part A

Determine the absolute pressure on the bottom of the swimming pool.

Express your answer to two significant figures and include the appropriate units.

Part B

Calculate the total force on the bottom of the swimming pool.

Express your answer to two significant figures and include the appropriate units.

Part C

What will be the pressure against the side of the pool near the bottom?

Express your answer to two significant figures and include the appropriate units.

Explanation / Answer

pressure due to weight of water in swimming pool

=gH

=1000*9.81*2.9=28449Pa
absoulte pressure on bottom of pool = 1.013*105 + 28449 = 129749Pa

PartB
Total force on bottom of pool =Pressure * Area

(129749)(34.0)(8.5) = 37497461 N  

Part C

The absolute pressure near bottom would be the same answer as 1) and just the water pressure =129749 Pa
