CULTURAL QA 08-2023-9 Q1 Why are the cabin walls on a cruiseship so thin?
A1 RebeccaWilliams, knows about boats and ships Jul 22 The cabin walls on a cruise ship are so thin because ofseveral reasons. Cruiseships are designed to be as light as possible, while still being strong andsafe. The weight of the ship affects its speed, fuel efficiency,stability, and maneuverability. Cruise shipbuilders use thin metal frames forthe cabins, which reduce weight and save space. The metal frames are also fireproof, which is an importantsafety feature. Cruise ships havelimited space to accommodate thousands of passengers and crew members, as wellas various facilities and amenities. The cabins are one of the most space-consuming parts of theship, so they need to be compact and efficient. By using thin walls, cruise ship builders can fit morecabins on each deck, and offer more options and categories for differentbudgets and preferences. The thin walls also allow for more flexibilityand customization of the cabin layout and design. Cruise ships are veryexpensive to build and operate, so cruise lines try to minimize their costs andmaximize their profits.One way to do that is to use thin walls for the cabins, which are cheaper andeasier to install and maintain than thicker walls. The thin walls also reducethe material and labor costs of the ship's construction and renovation. Thesavings can then be passed on to the passengers in the form of lower fares orbetter services. There are also somedrawbacks to having thin cabin walls. One is that they can be easily damaged,especially if a passenger accidentally bumps into them. Another is that they can allownoise to travel between cabins, which can be annoying for passengers who aretrying to sleep. Q2 What is the reason for the thickerwires in high power systems? A2 InfoSage,Professional Maven16h Reasons for Thicker Wires in High-Power Systems: Reduced Resistance andVoltage Drop:Thicker wires have lower electrical resistance compared to thinner wires. In high-powersystems, where significant current flows, minimizing resistance is crucial toprevent voltage drop. Voltage drop can lead to inefficient power transmissionand reduced performance of connected devices. HeatDissipation:Thicker wires have a larger surface area, allowing them to dissipate heat moreeffectively. In high-power systems, where currents can generate substantialheat, using thicker wires helps prevent overheating and potential damage to thewiring. Lower TemperatureRise:When high currents flow through a wire, resistance causes the wire to heat up. Thicker wiresexperience a lower temperature rise for the same current, enhancing theirsafety and reliability in high-power applications. EnhancedCurrent-Carrying Capacity:Thicker wires can carry higher currents without exceeding their ampacity(current-carrying capacity). In high-power systems, where currents aresubstantial, using thicker wires ensures that the wires can handle the loadwithout becoming a limiting factor. Minimized VoltageRegulation:Voltage regulation refers to maintaining a stable voltage level at different points in apower system. Thicker wires help reduce voltage fluctuations caused by loadvariations, ensuring consistent power delivery. Compliance withRegulations:Electrical codes and regulations often mandate the use of specific wire sizesbased on the power rating of the system. Thicker wires may be required to meetsafety and performance standards in high-power applications. LongerLifespan:Thicker wires experience less stress and wear due to their robustconstruction. This contributes to their longevity and reduces the need for frequentmaintenance or replacement. Lower ElectromagneticInterference (EMI):Thicker wires can help reduce electromagnetic interference generated by highcurrents, which can impact nearby electronic equipment and communicationsystems. My note- Thicker wiresminimises snapping due to storm etc. Q3 Why is vitamin B12 so dangerous? A3 DrChakweva, Dedicated & Determined - Visit my Bio Mon Vitamin B12 is an essential nutrient for the human body thatplays a critical role in several important functions, including producing red bloodcells, DNA synthesis, and nerve function. Unfortunately, vitamin B12 can be dangerous if nottaken in the appropriate dosage and at the right time. The most common risk associated with vitamin B12 is anoverdose. Too much of this nutrient can cause adverse effects likenausea, vomiting, and diarrhea, and even serious health issues such as liver orkidney damage. VitaminB12 is also unable to be adequately absorbed without certain acids found in thestomach or intestine, which can make the consequences of an overdose even moreserious. Another risk associated with vitamin B12 is the potentialfor interactions with other medications. While vitamin B12 is generally considered safe, it can react negatively with certainmedications, such as certain antibiotics and chemotherapy drugs. Thus,it’s important to speak to your doctor before combining vitamin B12 and anyother medications. It’s also important to note that some people have a greaterrisk of developing a vitamin B12 deficiency or experiencing an adverse reactionfrom taking a large dose of this nutrient. People with certain healthconditions, such as pernicious anemia, may have difficulty fully absorbingvitamin B12 from food, so they may be more likely to experience an overdose. In addition, vegans and vegetarians are at an increasedrisk for developing a vitamin B12 deficiency, and thus, might requiresupplementation of this nutrient. However, due to the risks associatedwith vitamin B12, it is important that these individuals speak to theirdoctor about the appropriate dosage and timing of supplementation. Overall, it’s important to recognize that vitamin B12 is anessential nutrient, but it’s also important to be aware of the potential risksassociated with taking too much of it. Speak to your doctor for guidance on howto best incorporate this nutrient into your diet or use supplementation ifnecessary. Q4 Does the flight crew change after a5-hour flight? A4 OdetteBishop, Cabin Crew Member (2018–present)9h I worked a 7:50 flightyesterday from New York City to Berlin, Germany. We obviously couldn’t just step out thedoor and leave, but on larger planes we have something called crew rest modules.Sometimes they are above or below the passenger compartments. After we have taken care of our main duties for the flight, a portion ofour crew will go on rest, while the rest will stay on duty. After their restperiod the other crew will switch and the next group will go on rest…. Q5 What are the benefits of purchasingan RO plant from authorized dealers compared to other sources? A5 GopalaKrishnan,Former Assistant General Manager 1996-2004 at Department of Telecom(1966–2004)Just now First of all you get the correct product under bill andwarranty. Mostly prize will be lesser than from other sources. But we have to takeit home, get company/authorized person installer, and mostly with A M C it willbe commissioned. Other sources, mostlyprocure from dealers,bring, install and charge for all work and cost together. Rarely, some may change new parts with old parts which no one canrecognize. Recently Ichanged all internal parts with new one in my RO system. Old and new lookedsame. Authorized service people will carry out service better. RO service and installation is competitive in my place Chennai. Service charges varyfrom 150–00 to 300. Aservice with 300-00 need not be better than a service of 150-00 All the above QA are from Quora website on 09-08- 2023. Quora answers need not be 100% correct answers . Compiled and posted by R.
