Find the velocity of a liquid density `800kg//m^3` from a tank in which the pressure of the liquid at the orifice is 480`N//m^3` above the atmospheric pressure.

The bulk modulus of a liquid is 2 xx 10^10 N/m^2 . What is the percentage decrease in the volume of the liquid , when the pressure is increased by 20 atmosphere > ( one atmosphere = 10^5 N /m^2 ).

The density of air near the earth's surface is 1.3kg m^-3 and the atmosphere pressure is 1.0xx10^5Nm^-2 . If the atmosphere has uniform density, same as that observed at the surface of the earth , what would be the height of the atmosphere to exert the same pressure .

Find the mass of 100cc of a gas if the RMS velocity of the molecules of gas at N.T.P. is 500m/s. Take normal atmospheric pressure as 1.013xx10^5 N/m^2 .

Find the mass of 15cc of a gas if the RMS velocity of the molecules of gas at N.T.P. is 400m/s. Take normal atmospheric pressure as 1.013xx10^5 N/m^2 .

What is the R.M.S. velocity of the molecules of a gas at N.T.P., if the density of gas at this temperature is 0.165 kg/m^3 ?

What is the R.M.S. velocity of the molecules of a gas at N.T.P., if the density of gas at this temperature is 0.165 kg/m^3 ?
