Find the pressure at a depth of 10 m in water if tre atmospheric pressure is 100kPa.
`[1Pa=1N//m] [100kPa=10^(5) Pa=10 ^(5) N//m^(2) =1 atm.]

Text Solution

Verified by Experts

The correct Answer is:
A
`P_(open)+(1)/(2)rhov^(2)=P_(closed)impliesV=sqrt((2(P_(closed)-P_(open)))/(rho))=sqrt((2xx(3.5-3)xx10^(5))/(10^(3)))=10m//s`

If the container filled with liquid gets accelerated horizontally or vertically, pressure in liquid gets changed. In liquid ( a_(y) ) for calculation of pressure, effective g is used. A closed box horizontal base 6 m by 6 m and a height 2m is half filled with liquid. It is given a constant horizontal acceleration g//2 and vertical downward acceleration g//2 . Water pressure at the bottomof centre of the box is equal to (atmospheric pressure =10^(5)N//m^(2) density of water =1000 kg//m^(3),g=10m//s^(2) )

An air bubble is lying just below the surface of water. The surface tension of water is 70xx10^(-3)Nm^(-1) and atmospheric pressure is 1.013xx10^(5)Nm^(-2) . If the radius of bubble is 1mm, then the pressure inside the bubble will be-

When water is boiled at 2 atm pressure the latent heat of vaporization is 2.2xx10^(6) J//kg and the boiling point is 120^(@)C At 2 atm pressure 1 kg of water has a volume of 10^(-3)m^(-3) and 1 kg of steam has volume of 0.824m^(3) . The increase in internal energy of 1 kg of water when it is converted into steam at 2 atm pressure and 120^(@)C is [ 1 atm pressure =1.013xx10^(5)N//m^(2) ]

Calculate the excess pressure withing a bubble of air of radius 0.1 mm in water. If te bubble had been formed 10 cm below the water surface on a day when the atmospheric pressure was 1.013xx10^(5)Pa then what would have been the total pressure inside the bubble? surface tension of water =73xx10^(-3)N//m
