Scenario 5: leaks after thirty batches
You notice that significant leaks are occurring during the plant’s testing and start-up
phases. These leaks are probably caused by the cheaper controls, inferior couplings, andthe inexperience of the plant operating team including Manuel. What should you do?
1. Have Manuel baby sit the batches timing them and constantly checking their temperature.2. Argue that it is necessary to immediately retrofit the plant with Lutz and Lutz
controls.3. Argue that it is necessary to retrofit the plant with Lutz and Lutz controls but thisshould be done after the plant has been turned over to operations. Let them pay for it.
Compare and rank these solution alternatives using the ethics and feasibility tests.
Scenario 6: should you let those plant jockeys make new stripper?
Wally: Well, this is what we’re going to give to operations when we hand over the plant. Is everybody okay it?
CHUCK: Fred's the guy who’s got to put his name on it, Fred’s got to be alright with it...Fred: Well, the couplings still leak when the pressure is up.
Wally: And we've alerted operations and given them specific instructions on how to maintain the connections.CHUCK: We've got Jen working on a lower temperature formula. That may make all of this moot.
Fred: We haven't worked out the bugs on the last step of the automation...WaLLY: And next year, we'll retrofit the entire plant with L and L controls.
CHUCK: This is how it works. We design it. We build it, we hand it over. They run it.We’ve done the best we can. No plant, no process, no system is ever completely perfect.
WALLY: You built a plant that’s efficient. You've got your upgrades to the wastewatertreatment.
Fred: Yeah, you're right. Um, for now Manuel or one of his guys can use the manualrelease valve.
CHUCK: Okay. Time to let those plant jockeys make New Stripper.You are Fred. Should you sign off on the documents?

Some closing exercises
- How does the STS in Morales, Mexico differ from that of Puerto Rico. (A suggested PR STS can be found on the last slide of the presentation appended just below.
- In what ways (if any) should the CIAPR code of ethics be changed to respond to the problems that arise in "Incident at Morales"? Is it necessary to add more specific principles of professional conduct? Should more aspirational, value-based provisions be added.
- Obviously, it is best to direct changes in our STSs to avoid problems like those arising in "Incident at Morales." What kind of changes should we make in the stakeholder columns? Can professional societies like the CIAPR play a role in preventing these problems? Is this primarily a compliance role or can other roles be identified?
Questions & Answers
Three charges q_{1}=+3\mu C, q_{2}=+6\mu C and q_{3}=+8\mu C are located at (2,0)m (0,0)m and (0,3) coordinates respectively. Find the magnitude and direction acted upon q_{2} by the two other charges.Draw the correct graphical illustration of the problem above showing the direction of all forces.
To solve this problem, we need to first find the net force acting on charge q_{2}. The magnitude of the force exerted by q_{1} on q_{2} is given by F=\frac{kq_{1}q_{2}}{r^{2}} where k is the Coulomb constant, q_{1} and q_{2} are the charges of the particles, and r is the distance between them.

what is the change in momentum of a body?
Capacitor is a separation of opposite charges using an insulator of very small dimension between them. Capacitor is used for allowing an AC (alternating current) to pass while a DC (direct current) is blocked.

which has a higher temperature, 1cup of boiling water or 1teapot of boiling water which can transfer more heat 1cup of boiling water or 1 teapot of boiling water explain your . answer
I believe temperature being an intensive property does not change for any amount of boiling water whereas heat being an extensive property changes with amount/size of the system.
Someone
temperature for any amount of water to boil at ntp is 100⁰C (it is a state function and and intensive property) and it depends both will give same amount of heat because the surface available for heat transfer is greater in case of the kettle as well as the heat stored in it but if you talk.....
Someone
about the amount of heat stored in the system then in that case since the mass of water in the kettle is greater so more energy is required to raise the temperature b/c more molecules of water are present in the kettle

Two bodies attract each other electrically. Do they both have to be charged? Answer the same question if the bodies repel one another.
No. According to Isac Newtons law. this two bodies maybe you and the wall beside you.
Attracting depends on the mass och each body and distance between them.

What is specific heat capacity
Specific heat capacity is a measure of the amount of energy required to raise the temperature of a substance by one degree Celsius (or Kelvin). It is measured in Joules per kilogram per degree Celsius (J/kg°C).
