Q2 How do you maintain and take care ofplumbing systems for your home? A2 Gopala Krishnan, Retired AGM BSNL justnow. Unless one is trained practically, one cannot do plumbinghimself perfectly. When trainedand experienced plumbers carrying out the work, one may feel so simple.But it is not so. Better established plumbers carry out workwith perfection and safely. I am answeringfrom Chennai, India. Established plumbers are mostly electricians cum plumbershere.Physical work is lesser in electrical works comparing to plumbing. So nowadays we have to pay through nose for plumbing works Q3 Why do planes board long before theirdeparture time and passengers end up waiting on board for the departure slot? A3 Vishnu Ravi, Aerospace Engineer |Aviation Enthusiast & Content Creator21h Unlock the secretsbehind why planes board well in advance of their departure time, causingpassengers to wait onboard for their designated slot. Prepare to be enlightenedwith these compelling insights gleaned from thorough research: Punctuality Matters: Airlines meticulously track on-timedepartures and arrivals, a vital metric for both management and passengersalike. To ensure a higherchance of punctuality, boarding commences earlier than strictly necessary.Timely arrival is closely intertwined with timely departure, particularly in bustling airports, where missing a departure slot could mean anhour-long wait. Boarding by Stairs: When a flight boards via stairson the tarmac instead of using a conventional gate, boarding naturally takeslonger as passengers need to be shuttled to the aircraft. In such instances,boarding gates close significantly earlier than usual, warranting a forewarningfor passengers. The Unwritten Final-Boarding Rule: Though flightshave a scheduled departure time, an unspoken final-boarding rule exists. Gate agents may close the aircraftdoors 10 minutes before departure, leading to either immense relief or adisrupted journey. To navigate this uncertainty, passengers are advised toarrive at the gate at least 30 minutes early and attentively listen toannouncements. Ground Stops: In the event of a ground-stop order,airlines may board passengers onto the plane, push back, and then await furtherinstructions. This practice, though aimed at minimizing delays, can befrustrating for passengers who prefer waiting in the terminal over beingconfined on the plane. Preparation for Pushback: Numerous factors canhinder aircraft preparation, thereby delaying takeoff. From loading cateringand disposing of used galley carts to cleaning the entire aircraft andrefueling, these tasks can take longer than anticipated. Even a seemingly minorissue, like a delay in aircraft cleaning due to staff shortages, can impactboarding time, potentially leading to a missed departure slot. In conclusion, a multitude of factors contribute toplanes boarding well ahead of their departure time and passengers experiencingonboard wait times. Understanding the need forpunctuality, the implications of boarding by stairs, the nuances of thefinal-boarding rule, the effects of ground stops, and the challenges ofaircraft preparation allows travelers to appreciate the complexities of airtravel and plan accordingly. Q4 Why impure metals corrode faster thenpure metals? A4 Erika Fernandez, Works at Freelancer,Novelist, Writer Jul 16 Corrosion affects metals mainly through electrochemicalreactions. Electrochemical reactions involve thetransfer of electrons between two substances that have different electricalpotentials. Whena metal is exposed to an electrolyte, such as water or moisture, it can form anelectrochemical cell with another metal or substance that has a differentelectrical potential. The metal that has a higher electrical potential will actas an anode and lose electrons to the other substance that acts as a cathode. The loss of electrons causes themetal atoms to oxidize and form metal ions that dissolve in the electrolyte orform corrosion products, such as rust or scale. The impurity of ametal can influence its corrosion rate by creating heterogeneity or differencesin its composition or structure. Impure metals can contain various elements or compounds that havedifferent electrical potentials than the base metal. These impurities can act as anodes or cathodes within the metal andcreate micro-electrochemical cells that accelerate the corrosion process. For example, iron that contains carbon,sulfur, phosphorus, or other elements can corrode faster than pure iron becausethese elements can form local anodes or cathodes that enhance the oxidation ofiron. Q5 Why does the Earth look flat whileflying an airplane? A5 Rebecca Williams,Experience inAviation Jul 21 The Earthlooks flat while flying an airplane because of two main reasons: the size ofthe Earth and the altitude of the airplane. The Earth is very large compared to the size of anairplane or a human. Its radius is about 6,370 km(3,960 miles), which means that its circumference is about 40,000 km (24,860 miles).To see the curvature of the Earth, you would need to see a significantportion of this circumference, which is not possible from a low altitude. The altitudeof an airplane is usually between 9,000 and 12,000 m (30,000 and 40,000 ft),which is very high for humans but not very high for the Earth.At this altitude, the horizon is about 360 km (220 miles) away from theairplane, which is only about 0.9% of the Earth’s circumference. This means that the curvature of the Earth is very subtle and hard tonotice from this distance. To see thecurvature of the Earth more clearly, you would need to fly much higher than atypical airplane. According to some calculations andobservations, the minimum altitude at which curvature of the horizoncan be detected is at or slightly below 10,600 m (35,000 ft), provided that the fieldof view is wide (60 degrees) and nearly cloud-free. But, this wouldstill be a very faint curve that may not be obvious to everyone. To see a more pronounced curve of the Earth, you wouldneed to fly even higher than that. For example, at15,500 m (51,000 ft), which is the highest ceiling of any production airplane,the curvature of the Earth is quite easy to see, especially if you have a widefield of view of 300 degrees or so. But, this altitude is not accessible tomost commercial or private airplanes. To see a truly spectacular view of the Earth’s curvature,you would need to fly into space. The boundarybetween the Earth’s atmosphere and outer space is called the Kármán line, and it islocated at 100 km (62 miles) above sea level. From this altitude and beyond,you can see the Earth as a spherical planet with a thin blue layer ofatmosphere around it. All the above QA are from Quora website on 01-08- 2023.
