3. A tank with its top open to the atmosphere contains liquid methanol (CH3OH, molecular weight 32g/mol) at the bottom of the tank. The tank is maintained at 30 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 CH3OH vapors are immediately dispersed once they exit the tank. At 30 C, the vapor pressure exerted by liquid CH3OH is 163 mmHg and at 40 C the CH3OH vapor pressure is 265 mmHg. We are concerned that this open tank may be emitting a considerable amount of CH3OH vapor. (2+2+2)
