What type of magnet attracts iron? Ferromagnetic materials such as iron, nickel and cobalt are therefore attracted to magnets, as well as rare-earth metals like gadolinium, neodymium and samarium. Can a magnet attract iron? Magnetic Field, Magnetic Field, 1) When two magnets are brought near each other, like poles repel; opposite poles attract. 2) When […]
What is Fe2O3 xH2O?
What is Fe2O3 xH2O? Fe2O3. xH2O is usually called hydrated ferric Oxide. It is a hydrated crystal. When Ferrous ion forms an ionic bond with Oxygen, it is called Ferrous Oxide. What are the conditions required for rusting? Rusting is an oxidation reaction. The iron reacts with water and oxygen to form hydrated iron(III) oxide, […]

What are the types of valves?
What are the types of valves? Common types of valves include: Ball Valve. Predominantly equipped with quick-acting 90-degree turn handles, these valves use a ball to control flow to provide easy on-off control. Butterfly Valve. Check Valve. Gate Valve. Knife Gate Valve. Globe Valve. Needle Valve. Pinch Valve. What are the three types of valve […]
What is the formula for calculating principal payment?
What is the formula for calculating principal payment? What Is Your Principal Payment? The principal is the amount of money you borrow when you originally take out your home loan. To calculate your principal, simply subtract your down payment from your home’s final selling price. For example, let’s say that you buy a home for […]
What are the 3 types of tolerances?
What are the 3 types of tolerances? A tolerance is an acceptable amount of dimensional variation that will still allow an object to function correctly. Three basic tolerances that occur most often on working drawings are: limit dimensions, unilateral, and bilateral tolerances. What is definition of tolerance? 1 : capacity to endure pain or hardship […]

Can a tight serpentine belt cause loss of power?
Can a tight serpentine belt cause loss of power? If the belts are too tight, they can put a strain on the shaft (and its bearing) of the alternator, power-steering pump and even the water pump. How long does a serpentine belt usually last? 60,000 to 100,000 miles What happens if serpentine belt breaks while […]
How are conductor sizes expressed?
How are conductor sizes expressed? Conductor sizes are expressed in American Wire Gage (AWG) or in circular mils. Conductor sizes found in Chapter 9, Table 8 of the National Electrical Code® start with 18 AWG (the smallest size) and end up at 2000 circular mils (the largest size). How is wire diameter expressed in the […]
How does fouling factor affect heat transfer?
How does fouling factor affect heat transfer? The deposition of any undesired material on heat transfer surfaces is called fouling. Fouling increases the overall thermal resistance and lowers the overall heat transfer coefficient of heat exchangers. Fouling also impedes fluid flow, accelerates corrosion and increases pressure drop across heat exchangers. What are the common causes […]
