Under the isothermal condition, a vertical tube of length L = 100 m contains a gas of molecular weight equal to 60

Q. Under isothermal condition, a vertical tube of length L = 100 m contains a gas of molecular weight equal to 60. The pressure and temperature at the top of the tube are 100 kPa and 25 ^oC respectively. Consider the universal gas constant and acceleration due to gravity as 8.314 J mol^-1 K^-1 and 9.81 m s^-2 respectively. If the gas is ideal, the pressure (in kPa) at the bottom of the tube will be

Ans: 102.37 to 102.44
