Inspector Sgt. Ambercromby of Scotland Yard. It is believed, although never proven, that Bonnie murdered her first husband, Lefty, by poisoning the tepid brandy they drank together on their first anniversary. Lefty was unaware she had coated her glass with an antidote before she filled both glasses with the poisoned brandy. Bonnie married her second husband, Clyde, and some years later when she had tired of him, she called him one day to tell him of her new promotion at work and to suggest that they celebrate with a glass of brandy that evening. She had the fatal end in mind for Clyde. However, Clyde suggested that instead of brandy, they celebrate with ice-cold Russian vodka and they down it Cossack style, in one gulp. She agreed and decided to follow her previously successful plan and to put the poison in the vodka and the antidote in her glass. The next day, both were found dead. Sgt. Ambercromby arrives. What are the first three questions he asks? What are two possible explanations? Based on what you learned from this chapter, what do you feel Sgt. Ambercromby suggested as the most logical explanation?

- LATIHAN 8.5-4. Concentration of NaOH Solution in Triple-Effect Evaporator. A forced-circulation triple-effect evaporator using forward feed is to be used to concentrate a 10 wt % NaOH solution entering at 37.8°C to 50%. The steam used enters at 58.6 kPa gage. The absolute pressure in the vapor space of the third effect is 6.76 kPa. The feed rate is 13 608 kg/h. The heat-transfer coefficients are U₁ = 6246, U2 = 3407, and U3 = 2271 W/m² K. All effects have the same area. Calculate the surface area and steam consumption. 8.5-1. Boiling Points in a Triple-Effect Evaporator. A solution with a negligible boiling- point rise is being evaporated in a triple-effect evaporator using saturated steam at 121.1°C (394.3 K). The pressure in the vapor of the last effect is 25.6 kPa abs. The heat-transfer coefficients are U₁ = 2840, U₂ = 1988, and U₁ = 1420 W/m² K and the areas are equal. Estimate the boiling point in each of the evaporators.arrow_forwardThe power generation unit in a plant uses a hot exhaust gas from another process to produce work. The gas enters at 10 bar and 350°C and exits at 1 bar and 40°C. The process produces a net amount of work equal to 4500 J/mol and it exchanges an unknown amount of heat with the surroundings. 1.1 Determine the amount of heat exchanged with the surroundings. Is this heat absorbed or rejected by the system? 1.2 Calculate the entropy change of the exhaust gas. 1.3 As a young and ambitious chemical engineer, you seek ways to improve the process. What is the maximum amount of work that you could extract from this system? Assume that the inlet and outlet conditions of the exhaust gas remain the same. Additional data: Assume the surroundings to be at the constant temperature of 298 K and the exhaust gas to be ideal with CP = 29.3 J/mol.Karrow_forwardLatihan mandiri Reaktor fluidisasi menggunakan katalis padat dengan diameter partikel 0,25 mm, rapat massa 1,50 g/ml, sperisitas 0,90.

- We have a feed that is a binary mixture of methanol and water (55.0 mol% methanol) that is sent to a system of two flash drums hooked together. The vapor from the first drum is cooled, which partially condenses the vapor, and then is fed to the second flash drum. Both drums operate at a pressure of 1.0 atm and are adiabatic. The feed rate to the first drum is 1000.0 kmol/h. We desire a liquid product from the first drum that is 30.0 mol% methanol (x1 = 0.300). The second drum operates at a fraction vaporized of (V/F)2 = 0.250. The equilibrium data are in Table 2-8. Find the following for the first drum: y1, T1, (V/F)1, and vapor flow rate V1.
