What are cookies? Explain it.

Do not confuse with biscuits; However, cookies or biscuits are come with small pieces and we usually like them.

Cookies are essentially pieces of code saved by websites onto the user’s web browser when a session is initiated. 

All websites that use Cookies have agreed that Cookies enhance the browsing experience by allowing a website to store small snippets of data on a user’s device. 

By doing so, the website can keep track of a user’s preferences and tailor content accordingly. According to W3 techs, cookies are used by 40.8% of all websites.

They are used to hold a modest amount of data specific to a particular client and website and can be accessed either by the web server or by the client computer

When cookies were invented, they were basically little documents containing information about you and your preferences.

Cookies are not programs, they do not perform any functions. These are simple text files that can be opened using Notepad. In ad tech, cookies are used to track users across the web. For instance, if a user visits a website, then the cookies of that website will be saved on the browser.

Now when the user visits the website again after a few days, the website will know it is the same user. Some cookies can track users across websites and devices.



For instance, when you select your language in which you want to view your website, the website would save the information in a document called a cookie on your computer, and the next time when you visit the website, it would be able to read a cookie saved earlier. That way the website could remember your language and let you view the website in your preferred language without having to select the language again.

A cookie can contain any type of information such as the time when you visited the website, the items that you added into your shopping basket, all the links you clicked in website, etc.

What is dead-heading a pump?

A dead-head is caused when a centrifugal pump operates with no flow through the pump due to a closed discharge valve or blockage in the line. The pump is forced to circulate the pumped medium, causing the temperature to continually rise. As the fluid churns inside the pump it heats into a vapor. Once a vapor is created, any bushings or mechanical seals in the pump heat to the point that they begin to crack, shatter, score or compromise the elastomers - killing the pump. When a centrifugal pump is dead-heading, it can lead to explosions, due to the energy being put into the liquid in the pump. Hydraulic overpressure and possible chemical reactions in the pump can also be caused by the overexertion of pressure. The same results can be caused by running the pump dry for an extended period - which can lead to cavitation.

Difference between SS316 and SS316L. what is the selection criteria?

𝐒𝐭𝐚𝐢𝐧𝐥𝐞𝐬𝐬 𝐬𝐭𝐞𝐞𝐥 𝟑𝟏𝟔/𝟑𝟏𝟔 𝐋: Stainless steel 316 and 316L are both austenitic stainless steels with similar compositions, but they have some key differences. The "L" in 316L stands for "low carbon," indicating that it has a lower carbon content than 316. 𝕊𝕥𝕒𝕚𝕟𝕝𝕖𝕤𝕤 𝕊𝕥𝕖𝕖𝕝 𝟛𝟙𝟞: ▪️Composition: Contains about 16-18% chromium, 10-14% nickel, 2-3% molybdenum, and small amounts of other elements. 👉🏼Use: Widely used in chemical processing equipment, pharmaceuticals, and marine applications. Commonly used in situations where exposure to harsh chemicals and corrosive environments is expected. Suitable for high-temperature applications. 𝕊𝕥𝕒𝕚𝕟𝕝𝕖𝕤𝕤 𝕊𝕥𝕖𝕖𝕝 𝟛𝟙𝟞𝕃: Composition: Similar to 316 but with a lower carbon content (max 0.03% compared to 0.08% in 316). 👉🏼Use: Preferred in applications where welding is required, as the lower carbon content minimizes the risk of carbide precipitation and subsequent corrosion.
