A 26-yeаr-оld mаn with а histоry оf cocaine use is being rushed to the emergency department after complaining of the worst headache of his life and quickly thereafter becoming unresponsive. No trauma to the head was noted. What is the most likely diagnosis?
A lоcаl municipаlity hаs cоntracted with yоur firm to design an induced-draft, counter-current, ammonia stripping tower at their water reclamation facility that has a permitted capacity of 5.0 MGD. Pertinent design data as follows: Average air and water temperature: 20 °C Wastewater pH: 11.0 Local atmospheric pressure: 725 mmHg Design hydraulic loading: 2.5 gpm/ft2 Design/theoretical air flow: 1.70 From the table, the partial pressure of ammonia at 20 °C is 0.03 mmHg and the ammonia concentration in the wastewater at 20 °C is 50×10-6 gNH3/gH2O (5 pts) Determine the equilibrium mass of ammonia in the air (Y2) (5 pts) Determine the air to water ratio (lb Air/lb H2O) (5 pts) If the G/L=2.0613 lb Air/lb H2O, determine the theoretical air required (Gtheor) (unit: lb Air/ft2hr). Hint: determine the mass flow rate of water (L) first. (5 pts) If the theoretical air required (Gtheor) is 2,580 lb Air/ft2hr, determine the “design” air required (lb Air/ft2·hr). (5 pts) If the design air flow required is determined to be 750 cfm/ft2, what is the design air flow required (Air/Gallon)? (unit: ft3/gallon)
