Kenny Videnia, a film producer, has to decide whether to bid for the film rights of a modestly successful novel. He believes that there is a 0.9 chance that he will be successful. If the bid is unsuccessful he will have to meet legal and administrative costs of $0.5m. If he is successful he has to decide whether to engage a big star for the main role. If he hires a big star the probability that the movie will be successful and make a profit of $50m is 0.3 and the chance that it fails and makes a loss of $20m is 0.7. If he doesn't hire a big star there is a 0.2 chance of the film making a profit of $30m and a 0.8 chance that it makes a loss of $10m.
(a) Suggest what Kenny should do using a decision tree.
(b) How sensitive is your advice to changes in the probability of the film making a profit if Kenny does not hire a big star?
Estimate the temperature of saturated steam which must be used when the exchanger is new (i.e., no scale present) if the water enters the unit at a rate of 15,000 gph and is heated from 70 to 150°F.
Design a reactor system to produce 40 metric tons per year of riboflavin using the strain given in the patent.
Calculate the time required for the dissolution of the solid. The Sherwood number correlation in Example 3.4 (B. K. Dutta) can be used. (Solution density = 1000 kg/m3 )
Using the data below, calculate graphically the number of theoretical plates needed using an L/D of 1.6 times the minimum Reflux ratio Rm.
Steam enters a nozzle at 800 kPa and 553.15 K (280°C) at negligible velocity and discharges at a pressure of 525 kPa. Assuming isentropic expansion of the steam in the nozzle,
Outline the provisions of Occupational Safety and Health Act 2005 with regard to Substances hazardous to health Describe four types of hazard which arise from the use of chemicals
For a gain of 0.5, derive the gain margin and phase margin of the systems of Problem 4.6 analytically. Let T =5 1 with no loss of generality because the value of ωT in radians is all that is needed for the solution.
What is element X? Propose a name for H2X? To completely neutralize a sample of H2X, 35.6 mL of 0.175 M OH solution was required. What was the mass of the H2X sample used?
For the rocket in Problem 6 determine the approximate chamber pressure, thrust, and duration at 245 and 328 K. Assume the temperature sensitivity (at a constant value of Ab /At) of 0.01%/K does not change with temperature.
If the system initially contains 5 mol HCl for each mole of oxygen, what is the composition of the system at equilibrium? Assume ideal gases.
The average energy required to free an electron from the dynode surface is 10 eV. For each incident ectron released from rest, how many electrons are freed at the first dynode? At the last dynode?
