A tank with its top open to the atmosphere contains liquid methanol (MeOH, molecular weight 32g/mol) at the bottom of the tank. The tank is maintained at 308 °C. The diameter of the cylindrical tank is 1.0 m, the total height of the tank is 3.0 m, and the liquid level at the bottom of the tank is maintained at 0.5 m. The gas space inside the tank is stagnant and the MeOH vapors are immediately dispersed once they exit the tank. At 308 °C, the vapor pressure exerted by liquid MeOH is 163 mmHg and at 408 °C the MeOH vapor pressure is 265 mmHg. We are concerned that this open tank may be emitting a considerable amount of MeOH vapor. What is the emission rate of MeOH vapor from the tank in units of kg MeOH/day when the tank is at a temperature of 308 °C? State all assumptions and boundary conditions. kindly answer this mass transfer problem on Stagnant Diffusion

Question
A tank with its top open to the atmosphere contains liquid methanol (MeOH, molecular weight 32g/mol) at the bottom of the tank. The tank is maintained at 308 °C. The diameter of the cylindrical tank is 1.0 m, the total height of the tank is 3.0 m, and the liquid level at the bottom of the tank is maintained at 0.5 m. The gas space inside the tank is stagnant and the MeOH vapors are immediately dispersed once they exit the tank. At 308 °C, the vapor pressure exerted by liquid MeOH is 163 mmHg and at 408 °C the MeOH vapor pressure is 265 mmHg. We are concerned that this open tank may be emitting a considerable amount of MeOH vapor. What is the emission rate of MeOH vapor from the tank in units of kg MeOH/day when the tank is at a temperature of 308 °C? State all assumptions and boundary conditions.
