...Boswell Plumbing Products Boswell Plumbing Products produces a variety of valves, connectors, and fixtures used in commercial and residential plumbing applications. Recently a senior manager walked into the cost accounting department and asked Nick Somner to tell her the cost of the D45 valve. Nick quickly replied, “why do you want to know?” Noticing that the manager appeared somewhat startled by this question, he explained, “The cost information you need depends on the decision you’re going to make. You might be thinking of increasing a scheduled production run of 3000 D45s by 100 units or scheduling an additional production run, or you might even be thinking of dropping the product. For each of these decisions, the cost information that you need is different.” Required Using the concept of incremental analysis, expand on Nick’s response of “Why do you want to know?” What cost information would be relevant to a decision to drop the product that would not be relevant to a decision to increase a production run by 100 units? According to the text, incremental analysis is the appropriate way to approach the solution to all business problems. It involves the calculation of the difference in revenue and the difference in cost between decision alternatives. The difference in revenue is the incremental revenue of one alternative over another, whereas the difference in cost is the incremental cost of one alternative over another. If an alternative yields an incremental...

Build on the trainer the hydraulic circuit shown in the figure below, using the components listed here. hydraulic power unit (2) pressure gauges flow control valve (FCV) – simulated load flow-meter Page 1 of 2 2. Initial setup: a. Fully close (CW) the FCV, and fully open (CCW) the pressure relief valve on the power unit. b. Start the power unit, and slowly adjust the pressure relief valve until pressure gauge P1 reaches 50 bar. Let the unit run for a few minutes then check and adjust P1 if necessary. c. Do not touch the pressure relief valve for the remainder of the lab. d. Fully open the FCV. 3. Test: a. Record the pressures P1, P2 and the flow rate under the “Min.” column in the table below. b. Slowly turn the FCV CW, adding a simulated load to the system. When the pressure at P1 increases to 15 bar, stop and record pressure P2 and the flow rate. c. Repeat for all columns listed in the table. The final column, listed as “Max Pres.” should be run with the FCV fully closed. Note the sound of the power unit during this test.

...BONUS ASSIGMENT BUSI 3040U: INFORMATION SYSTEMS PRIVACY VIOLATIONS AND THEIR RAMIFICATIONS ADEDAMOLA MAKINDE S/N 100367804 EI fraud investigator axed for leaking “quota” details This is the story of a private information leak by an employee of Service Canada. In February, Ms. Therrien went directly to the press and provided documents that were not authorized for public disclosure. Ms. Therrien leaked documents exposing a conservative crackdown on those receiving EI. The documents showed that EI investigators had been told to crackdown on about $485,000 in EI fraud each year. She further disclosed to the press that “fraud quotas” were just one of a culture in her office that encouraged benefits from as many recipients as possible to save money. As initial investigation was going on, she was suspended from her Job without pay from February 2013 until October 2013 when she was finally fired from the job. The letter sent on behalf of Employment and Social development Canada stated that she no longer met the conditions of her job. Certain control measures could have been taken to prevent this leak. The lady told the press that she felt bad that the government was not doing a good job by cutting down on EI payments. Her intention was good from what she told the press. In other words, these were private documents that involve government files and private files. There is no right for her to disclose any document that she is not authorized.

...Bottled water Vs Tap Water? Abstract This is a repot about what is better Bottled water or tap water. This report will show that for the most part there is no difference for your health but a big difference in price. So it will show that tap water is better for the most part. What is better Bottled water or Tap Water? What is better tap water or bottled water? People spend a lot of money on bottled water so some people think it’s better, but is it? All Tap and Bottled water is different so if you really want to know get the water tested. Bottled water is less regulated than tap water. Tap water is regulated by the EPA while bottled water is regulated by the FDA. The FDA tries to meet the EPA standard. Bottled water has a loophole so if it’s sold in the state it’s made then it’s not tested.[1][4] There have been some recalls of bottled water[2] Bottled water can go bad. Some of the plastic can get into the water, if you leave it outside.[4] don’t store Bottled water in hot places. Tap water will get metals in it from pipes. So if you have bad piping you may want to buy bottled water, but bottled water might not be better its tested way less,[5] so before you change to bottled water check to see if the brand is better than the Tap. Fluoride isn’t in some Bottled water. Fluoride is really good for your teeth. One of the top medical achievements of the 21st century according to the CDC. The cost of bottle water is more than Tap water. Tap water is cents for a gallon...

...The Concept of Adaption JoAnn Wade American InterContinental University Online December 9, 2013 The Concept of Adaption The first experiment that was performed was rubbing a finger gently over a piece of very coarse sandpaper a few times and rates its coarseness on a scale from 1 being very soft to 7 being very coarse. Then after a minute or two, rub the same finger over the paper and again rate its coarseness. The first time the perception rating was a 6 or a 7, very coarse. After a minute or two the same finger was rubbed along the sandpaper again. This time the rating was a 3 or a 4 softer than the first time. The reason for the rating scale to have lowered was that the finger had adapted to the coarseness of the sandpaper. It still felt the roughness of the paper but it was not as rough the second time. The second experiment was to prepare one cup of sugar water and one with fresh water. Take a sip of the sugar water and swish it around in your mouth for several seconds without swallowing it. Gradually, it should taste less sweet, dispose of the water. Taste the cup containing fresh water. With the sugar water your mouth became adapted to the taste of the sweetness. The second taste of the fresh water was a surprise because your mouth had become adapted to the sugar water and the fresh water was a sudden, different change. The third experiment was fill three medium-sized bowls as follows: bowl 1 with very hot tap water; bowl 2 with very cold tap water; bowl 3...

The gas used in this experiment is air. The elbow meter was also calibrated and the fanning friction factor across the pipe was calculated. The friction loss due to the velocity head through the straight pipe and other fittings was also calculated. Theory and Nomenclature To measure the gas flow in a pipe, an annubar is used. An annubar is a set of Pitot tubes mounted across a pipe. It measures the differential pressure between the static pressure and the full pressure of the stream. The Pitot tube’s full pressure chamber opening is facing against the stream so that is allows for conical aerodynamics. Applying Bernoulli’s principle and varying the pressure difference calculated...
