What is the absolute pressure

experienced at a bottom of a

swimming pool 9 meters in depth?

An airplane in level flight whose mass

is 20,000kg has a wing area of 60 m^2.

What is the pressure difference the

upper and lower surface of wings?

( for a solid surface , pressure= force /area)

Calculate the absolute pressure

at the bottom of this swimming pool.

(density of water=1000kg/m^3,

atmospheric pressure is 1.01*10^5 N/m^2)

a) at the shallow end

b) at the deep end

Find the pressure (in pascals) produced by a

kilogram of nickel on a horizontal

surface if the area it rests on
is 370 cm^2

At what depth below the surface of the

ea is absolute pressure five times

atmospheric pressure?
Atmospheric pressure is 101325 Pa.

Density of sea water is 1039 kg/m3.

In a hydraulic lift a force F1 = 510 N is applied to a piston

with area A1 = 1200 cm2. If the force on the
other piston is 2168 N,

find the area of the other piston

In a hydraulic lift a force F1 = 320 N is

applied to a piston with area A1 = 0.07 m^2.

If the area of the other
piston is 0.46 m^2,

find the force on the other piston.
