Dimensions of a swimming pool are 28.0 m by 9.5 m and its uniform depth is 2.9 m . The atmospheric pressure is 1.013×10^5N/m^2 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 side of the pool near the bottom?

Assume that the left side of your heart creates a pressure of 121 mm Hg by exerting a force directly on the blood over an effective area of 16.0 cm2. What force (in N) does it exert to accomplish this? N

A liquid-filled tube called a manometer can be used to measure the pressure inside a container by comparing it to the atmospheric pressure and measuring the height of the liquid. Such a device (filled with water) is shown in the figure, measuring the pressure inside a balloon filled with an unknown gas. The water level on the side of the manometer which is open to the air is 22.3 cm higher than on the side connected to the balloon. a) Find the gauge pressure in the balloon, in units of Pa. Recall the density of water is 1000 kg/m3.  b) Find the absolute pressure in the balloon, in units of Pa.

A vacuum-style lift assist exerts a vertical force on an object by attachment of one or more suction cups to the top of that object. For a lift with four suction cups to provide at least 500 N of lifting force, what is the minimum vacuum pressure (mm Hg) allowable inside each 76-mm-diameter cup attached to the object? Pcup i mm Hg

Water travels through a pipe at 9.11 m/s. The pipe contracts from a crossectional area of 1.9 m2 to an area of 0.211 m2.   a) What is the speed of the water in the second part of the pipe in m/s?  m/s   b) How much is the pressure change in KPa as the pipe contracts? The density of water is 1000 kg/m3. Enter a positive value for an increase in pressure, a negative value for a decrease.  kPa

A child is playing with a 0.5 kg ball in the swimming pool. The ball is made of a stiff rubber and has a radius of .25 m. Assume the volume of the ball does not change when held under water. What downward force must the child exert on the ball to hold it in equilibrium just below the surface of the water? a. b. How does this answer change if the child was holding the ball near the bottom of the pool (1.5 m down)?

Such a device (filled with water) is shown in the figure, measuring the pressure inside a balloon filled with an unknown gas. The water level on the side of the manometer which is open to the air is 12.2 cm higher than on the side connected to the balloon.    a. Find the gauge pressure in the balloon, in units of Pa. Recall the density of water is 1000 kg/m3.  b. Find the absolute pressure in the balloon, in units of Pa.

5. DETAILS 777777.78 Pa MY NOTES A 70.00kg ballroom dancer wearing high heels accidentally steps on her partner's foot. If her entire weight was momentarily supported by the heel of her shoe, which has a surface area of 0.90 cm², what amount of pressure does this apply to her partner's foot? 762.22 Pa 76222.22 Pa 7622222.22 Pa ASK YOUR TEACHER Suppose she instead stepped on her partner's foot with her forefoot instead of her heel (i.e., larger surface area). Would the pressure on her partner's foot be greater, less than, or equal to if she stepped on her partner with her heel? The pressure from the forefoot would be greater than the pressure from her heel. The pressure from the forefoot would be equal to the pressure from her heel. The pressure from the forefoot would be less than the pressure from her heel.
