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
