At a depth of 1000 m in an ocean (a) What is the absolute pressure ? (b) What is the gauge pressure ? © Find the force acting on the window of area 20cmxx20cm of a submarine at this depth the interior of which is maintained at sea level atmospheric pressure. (the density of sea water =1.03xx10^(3)xx10^(3)kgm^(-3),g=10ms^(-2))

What is the density of water at a depth where pressure is 80.0 atm, given that its density at the surface is 1.03xx103" kg m"^(-3) ?

The lower end of a capillary tube of diameter 2.00 mm is dipped 8.00 cm below the surface of water in a beaker . What is the pressure required in the tube in order to blow a hemispherical bubble at the end in water ? The surface tension of water at temperature of the experiments is 7.30xx10^(-2)Nm^(9-1) . 1 atmospheric pressure =1.01xx10^(5)Pa . Density of water =1000kg//m^(3),g=9.80ms^(-2) . Also calulate the excess pressure .

The lower end of a capallary tube of diameter 2.50 mm is dipped 8.00 cm below the surface of water in a beaker .What is the pressure required in the tube in order to blow a hemispherical bubble at the end in water ? The surface tension of water at temperature of the experiments is 7.30xx10^(-2)Nm^(-1) . 1 atmospheric pressure 1.01xx10^(5)Pa . Density of water =1000kg//m^(3),g=9.80ms^(-2) .Also calculate the excess pressure .

Two narrow bores of diameters 3.00mm and 6.0mm are joined together to form a U-tube open at both ends. If the U-tube contains water, what is the difference in its levels in the two limbs of the tube? Surface tension of water at the temperature of the experiment is 7.3 times 10^-2 N m^-1 .Take the angle of contact to be zero and density to water to be 1.0 times 10^3 kg m^-3

A fully loaded boeing aircraft has a mass of 3.3 times 10^5 Kg . Its total wing area is 500 m^2 . It is in level flight with a speed of 960 km//h (a) Estimate the pressure difference between the lower and upper surfaces of the wings (b) Estimate the fractional increase in the speed of the air on the surface of the wing relative to the lower surface.[ The density of air is p= 1.2 kg m^-3 ]
