What is gauge pressure?

What is vapour pressure of a liquid?

An air bubble of radius 0.2 mm is situated just below the water surface. Calculate the gauge pressure. Surface tension of water = 7.2 xx 10^-2 N//m .

What is blood pressure? How is it measured? Explain factors affecting blood pressure.

What is absolute pressure at a depth h below the surface of the liquid?

What is the pressure on a swimmer 10m below the surface of lake? g=10ms^(-2) , atmospheric pressure = 1.01 xx 10^(5)Pa

300 cc of a gas is compressed to 150 cc at the atmospheric pressure of 10^6 dyne/ cm^2 . If the change is sudden, what is final pressure ? [Given gamma=1.4 ]

What is the pressure at the bottom of the ocean at a place where it is 3 km deep ? [atmospheric pressure =1.01 xx10^(5)Pa, Density of sea water =1030kg m ^(-3)]

With what velocity does water flow out of an orifice in a tank with gauge pressure 4xx10^5 N//m^2 before the flow starts? Density of water= 1000kg//m^3
