the aqueous humor in a person's eye is exerting a force of 0.469 N on the 1.21 cm^2 area of the cornea  a) what pressure is this in mm Hg?  b) is this value within the normal range for pressures in the eye? Yes or no

What is the average pressure on the soles of the feet of a standing 90.0 kg person due to the contrast force with the floor? Each foot has a surface area of 0.020m^2

The gauge pressure in a balloon in measured by means of an open-tube manometer that uses water (density = 1.00 x 10° kg/m'). What gauge pressure p is indicated by a difference of 0.0151 m in the heights of the water columns? Pa

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
