For the circuit depicted below, find the differential equation for i(t) (you don't have to solve it) $i_s$ 4 ? 0.5 H i
Question 1 (45 marks) An engineer planned to fill an open chemical dIPPING tank (LxWxH: 3m x 1m x 1m) to the brim with liquid benzene in a room that is 30m by 4m by 2.5m height. a) The filling was carried by an external tank connected to a small pump working at 5L/min. Do a thorough risk assessment for the activity of filling up the tank and support your analysis by estimating the likely benzene vapor concentration within the vicinity of the tank. Suggest and explain one safety precautions in light of your risk assessment. State your assumptions (if any). (20 marks) b) On one such filling occasion, the engineer forgot to switch on the ventilation system, 40 m³/min of air flow. i) After switching on the ventilation, what is the minimum length of time, the engineer needs to wait before the concentration falls to safe levels? Assume k = 0.5 for the room. In reality, why would it take a longer time that what was calculated? What could the engineer have done instead to shorten the actual time? (20 marks) ii) Once after switching on the ventilation, the engineer immediately stepped out to smoke at the ventilation outlet of the room. Analyze whether there is the possibility of a fire due to possible ignition source. (5 marks) Question 2 (55 marks) A spherical 10m inner diameter tank was used to store 95psig chlorine gas in a country whose ambient temperature can fluctuate between -15°F to 104°F. Occasionally there were temperature fluctuations that resulted in spikes in the tank pressure. A conventional spring-type pressure relief device with sizing area of 1.25 in² was
Assume that adults were randomly selected for a poll. They were asked if they "favor or oppose using federal tax dollars to fund medical research using stem cells obtained from human embryos." Of those polled, 484 were in favor, 399 were opposed, and 121 were unsure. A politician claims that people don't really understand the stem cell issue and their responses to such questions are random responses equivalent to a coin toss. Exclude the 121 subjects who said that they were unsure, and use a 0.05 significance level to test the claim that the proportion of subjects who respond in favor is equal to 0.5. What does the result suggest about the politician's claim? B. $H_o: p = 0.5$ $H_1: p < 0.5$ C. $H_o: p \neq 0.5$ $H_1: p = 0.5$ D. $H_o: p = 0.5$ $H_1: p \neq 0.5$ Identify the test statistic for this hypothesis test The test statistic for this hypothesis test is (Round to two decimal places as needed)
