Question

Determine the absolute pressure on the bottom of a swimming pool 26.0 m by 8.5 m whose uniform depth is 2.0 m .

Answer #1

Dimensions of a swimming pool are 34.0 m by 9.5 m and its
uniform depth is 1.8 m . The atmospheric pressure is
1.013×105N/m2.
A) Determine the absolute pressure on the bottom of the swimming
pool.
B) Calculate the total force on the bottom of the swimming
pool.
C) What will be the pressure against the sideof the
pool near the bottom?

A rectangular swimming pool is 8 m ✕ 34 m in area. The depth
varies uniformly from 1 m in the shallow to 3 m in the deep end.
(a) Determine the pressure at the deep end of the pool and at the
shallow end. (b) What is the net force on the bottom of the pool
due to the water in the pool? (Ignore the effects of the air above
the pool for this part.)

If you dive to 3 m below the surface of a swimming pool filled
with milk, (A) what is the pressure due to the milk alone? (B) What
is the total or absolute pressure at that
depth? (rmilk = 1033 [kg/m3]

(a) Calculate the absolute pressure at the bottom of a
freshwater lake at a point whose depth is 28.4 m. Assume the
density of the water is 1.00 103 kg/m3 and the air above is at a
pressure of 101.3 kPa.
(b) 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 32.2 cm?

The
atmospheric pressure above a swimming pool changes from 753 to 761
mm of mercury. The bottom of the pool is a 20.8 m x 37.9 m
rectangle. By how much does the force on the bottom of the pool
increase?

A silver coin sits on the bottom of a swimming pool that is 4
meters deep. A beam of light reflected from the coin emerges from
the pool making an angle of 20 degrees with respect to the water’s
surface and enters the eye of an observer. Extend this ray, which
goes from the water-air surface to the eye, straight back until it
intersects with the vertical line drawn through the coin. What is
the apparent depth of the swimming...

A swimming pool is 50 ft wide and 100 ft long and its bottom is
an inclined plane, the shallow end having a depth of 4 ft and the
deep end, 7 ft. Assume the pool is full of water. (Round your
answers to the nearest whole number. Recall that the weight density
of water is 62.5 lb/ft3.)
(a) Estimate the hydrostatic force on the shallow end.
(b) Estimate the hydrostatic force on the deep end.
(c) Estimate the hydrostatic...

a pool is 30.0 m long and 26.0 wide how many ml of water are
needed to fill the pool to an average depth of 8.65 ft
enter the answer in scientific notation
and ml unit

Measured along the surface of the water, a rectangular
swimming pool has a length of 17 m. Along this length, the flat
bottom of the pool slopes downward at an angle of 12 ° below the
horizontal, from one end to the other. By how much does the
pressure at the bottom of the deep end exceed the pressure at the
bottom of the shallow end?

An underwater laser light is at the bottom of a swimming pool,
and is pointed towards the surface. A light ray from the laser
makes an angle of incidence of ?i=350 at the
surface of the water. [Note: ??????=1.33;
????=1.00]
Calculate the angle of refraction of the laser light when it
emerges into the air above the water. Determine the critical angle
of incidence of the laser light to have Total Internal
Reflection.
