The function of the circle of Willis is to equalize blood pressure to the brain and provide an alternate blood source should one of the vessels involved be comprised.

Which of the following is a dip of the dura mater into the transverse fissure?

200 kmole/hr at 4 bar and 30 C containing 40% styrene, 25% methanol and 35% toluene (molar %) is sent to a pre-heater using heat recovered from the overhead product prior to being sent to a 21-stage distillation column with a total condenser and kettle reboiler as shown in the PFD below. The pre-heater is designed to heat the process liquid prior to the feed entering above stage 10. The distillate product is cooled to 35 C. The stage 1 pressure is 2.5 bar with a 0.2 bar drop across the condenser on the process side. The bottoms pressure is 3.5 bar. Use a mass balance to set either the distillate or the bottoms flow rate and then use a design specification such that styrene with a purity of 99.95% is to be recovered in the bottoms by varying the reflux ratio. Use the NRTL method with UNIFAC for estimation Use RADFRAC to model the column Use two heater blocks and a heat stream to model the pre-heater/product cooler heat exchange Ignore pressure drops in the heater blocks What is the temperature of the feed entering the column in oC?    __     _________________ What is the duty of the product cooler/pre-heater in GJ/hr?  _____         ______________ What is the reflux ratio required to achieve the desired product purity?   ________________ What is the energy consumption in the reboiler in GJ/hr for 99.95% pure styrene?_____           ___________________ What is the diameter in meter for this column if sieve trays with 4 tray passes and default tray spacing are used? ___       _______________

When considering precedent transactions, which question(s) would an investment banker typically ask to better understand the context of an M&A deal? Check ALL that apply:

Assume that a financial sponsor paid 2,400m total to purchase a business (in other words, the entry enterprise value was 2,400). The deal was financed with debt of 5.6x LTM EBITDA. LTM EBITDA at entry was 300 million. The total debt repaid over the holding period (3 years) is $360 million. The business is expected to be sold at the end of year 3 for an enterprise value of 3,000 million. What is the IRR? Express your answer as a percentage and round to the nearest tenth decimal place. For example, if your answer is 10.3%, then input “10.3”
