Question1: Cyclohexane liquid at 10 barg flows through a 1-cm-diameter hole to atmospheric pressure. Estimate the discharge rate if the ambient pressure is 1atm. Question2: 4-12. The morning inspection of the tank farm finds a leak in the turpentine tank. The leak is repaired. An investigation finds that the leak was 0.1 in. in diameter and 7ft above the tank bottom. Records show that the turpentine level in the tank was 17.3ft before the leak occurred and 13.0ft after the leak was repaired. The tank diameter is 15ft. Determine: a) the total amount of turpentine spilled. b) the maximum spill rate, and c) the total time the leak was active. The density of turpentine at these conditions is 55Ibm/ft3. Question3: Two liters of a liquid chemical is spilled on the laboratory floor. Assume 1atm of pressure and a temperature of 25C. - If the liquid pool is 2mm deep, calculate the area of the pool. - What ventilation rate, in m3/s, is required to prevent the air concentration from exceeding the TLV for the chemical of 100ppm ? Ventilation air is provided for the lab via a 0.5 -m-square duct. The air velocity exiting the duct is measured with a velometer at 30m/s. - Calculate the volumetric flow of air from this duct in m3/s. Is this adequate ventilation for this spill? Data for the liquid chemical: Molecular weight: 100 Saturation vapor pressure of chemical at 25C:100mmHg
