Chapter 1, Problem 6P
During a medical operation an anesthesiologist controls the depth of unconsciousness by controlling the concentration of isoflurane in a vaporized mixture with oxygen and nitrous oxide. The depth of anesthesia is measured by the patient's blood pressure. The anesthesiologist also regulates ventilation, fluid balance, and the administration of other drugs. In order to free the anesthesiologist to devote more time to the latter tasks, and in the interest of the patient’s safety, we wish to automate the depth of anesthesia by automating the control of isoflurane concentration. Draw a f unctional block diagram of the system showing pertinent signals and subsystems (Meier. 1992). (Section 1.4: Introduction to a Case Study]

3 A farmer has a 10-heactare maize farm. The maize is under “Fall Army Worm” attack. The farmer has to urgently control the attack using a chemical called AGENOX 221. Motorized sprayers with tank capacities of 15 litres each are to be used. The recommended concentration of the chemical is 2 ml/L and each full tank will cover ½ hectare. A 50-man team is engaged to control the attack. Using the above information and the assumptions given below:
i. What volume of the chemical is required to cover the entire field to control the “Fall Army Worm” attack?
ii. If each man covers an area of 25 m2 from one end of the field to the other, how many trips will each of them make to cover the entire field? Assume ach man moves in a straight line.
Assumptions:
1. The 10 ha farm is considered to be a perfect square.
2. There is a 2.5 % loss of chemical due to the transfer to the sprayer tank.

They make the following claims. 1. The pressure inside N₂-filled tires does not rise or fall with temperature changes. 2. Nitrogen leaks out of tires much more slowly than air because the N₂ molecules are bigger. 3. Nitrogen is not very reactive, and moisture and O₂ in air cause corrosion that shortens tire life by 25-30% Evaluate the claim as a whole. Check all that apply. Claim passes falsifiability test.
