See, the difference between *Raptor 1 and raptor 3 engines* used by *spaceX!* *RAPTOR 1 rocket engine 🚀* The full space version, seems like spaghetti 🍝 due to complex plumbing is the earliest engine prototypes used by spaceX. It could generate trust of about ~185 tons and pressure chambers ~250 bars. *RAPTOR 2 rocket engine 🚀* The raptor 2 was redesignet fo mass production due to ineffectiveness compared to raptor 1. This was much clearer design. The thrust generated: ~230 tons Pressure chamber: ~300 bars It contained better cooling and fewer welds. *RAPTOR 3 rocket engine 🚀* This is the most advanced and powerful iteration of raptors. Thrust generated: ~269 tons Pressure chamber: ~330 bars or higher The spaceX used the most advanced materials and 3d printerong technologies to make it possible. *The raptor engines are considered one of the most advanced rocket engines ever created even advanced then NASA's!*

*Ever wondered why we pour distilled water in an inverter battery?* Let's go through The mechanism of inverter batteries. The *GALVANIC AND ELECTROLYTIC CELL* * The GALVANIC OR VOLTAIC cell A *galvanic cell* is a device that converts chemical energy into electrical energy through a spontaneous redox reaction. 📌 Key Points: 1. Spontaneous reaction (ΔG < 0) 2. Produces electric current 3. Used in batteries (like dry cell, Daniel cell) 4. Anode is negative (oxidation occurs here) 5. Cathode is positive (reduction occurs here) *⚡️ ELECTROLYTIC CELL* An *electrolytic cell* is a device that uses electrical energy to drive a non-spontaneous redox reaction. 📌 Key Points: * Non-spontaneous reaction (ΔG > 0) * Requires external power source (like battery) * Used in electroplating, electrolysis of water, charging batteries * Anode is positive (oxidation still occurs here) * Cathode is negative (reduction still occurs here)

FACT OF INVERTER BATTERY: > While discharging, The battery works as galvanic cell! > While charging, The battery works as electrolytic cell! *????* _Why distilled water is used?_ *Since, inverter batteries use Aqueous Diluted Sulfuric acid, the electrolysis uses most of the water to break down in Hydrogen and oxygen.* *⚠️ Why not tap water?* Tap water contains impurities, salts, and minerals (like Ca²⁺, Mg²⁺, Cl⁻, etc.). These can: React with sulfuric acid Deposit on electrodes, reducing battery efficiency Corrode internal parts Shorten battery life

*Do not touch any kind of infection or squeeze acne or pimples in this red region!* Let's explore *TRAINGLE OF DEATH* It's an anatomical region in the face surrounding the _apex of nose (glabella) and between the edges of mouth_ Why *DEATH TRAINGLE DEATH ☠️* *In simple words:* This region contains anatomically unique venous blood vessels without any valves! > *The facial vein connects directly or indirectly to the cavernous sinus in the brain via the angular vein and superior ophthalmic vein.* > These veins are valveless, allowing retrograde flow (blood can flow backward). *Infections (like pimples or boils)* in this area can spread to the brain, leading to: - Cavernous sinus thrombosis - Meningitis - Brain abscess *Avoid:* Squeezing pimples, boils, or acne in this area. Facial trauma with open wounds, Infections from nasal furuncles or upper lip can lead to severity.
