When hydraulic system become dangerous?
The hydraulic system works is dangerous. If the holes are pressure hoses transmission oilis sprayed with high pressure and this is very dangerous.
How dirt is removed from clothes due to surface tension and surfactant and its mechanism?
The nonpolar part of soaps or detergents "dissolve" dirt, fats and oilis; this mixture reach the internal part of so-called micelles, formed by adding soaps to water. The external part of these micelles is from polar part of soaps and detergents and is soluble in water. So thhis assembly is washed.
What is petroleum oil?
Petroleum (L. petroleum, from Greek πετρέλαιον, literally "rock oil") or crude oilis a naturally occurring, flammable liquid consisting of a complex mixture of hydrocarbons of various molecular weights, and other organic compounds, that are found in geologic formations beneath the earth's surface.The term "petroleum" was first used in the treatise De Natura Fossilium, published in 1546 by the German mineralogist Georg Bauer, also known as Georgius Agricola.[1]
What is the use of Cascade tank in merchanet ship enige room?
Wasted steam drain which has heated fuel oil for the main engine etc., is led to the atmospheric condenser and cooled. Then, if any oilis mixed in the drain waterbecause of cracks in pipes(These cracks are not acceptable) is removed by sponges in the buckets provided in the cascade tank and cleaned water is fed to the auxiliary boiler by feed pump.The water also heated to approximately 90 deg C to oxygen in the feed water .
Is solar power renewable resource?
It does not need to be renewed, it is constantly available as long as the sun is shining. And that will last several more billion years.Solar power is energy collected from the sun. While not 100% renewable, as long s we have sun and a planet to live on, we will have this virtually unlimited power source.
What does it mean when my car is knocking in the head and blowing white smoke but not overheating?
If the vehicle is knocking it depends on where the location of the knocking sound is coming from if it is coming and what type of engine it is in other words1) Is it a (DOHC) Double Over Head Camshaft Engine.2) Is it a (SOHC) Single OVer Head Camshaft Engine.These two choices are the topend of your engine3) Is it a In Block Camshaft Engine.This choice is the bottom end of your engineIf your engine is one of the first two choices listed above the problem can be either a valve has bent or broken off and is being tossed around in the combustion chamber or what is known as the TopEndIf your engine is number three choice a push rod has been broken(These are the most common problems)Now if the engine is inblock cam a push rod may be bent or a valve might also be broken.But to give some better direction if your engine is blowing whit smoke and making a knocking noise you might have burnt or sticking valves along with a blown head gasketa cracked engine block or cracked cylinder head.There are several ways to test and diagnose your problem one check your spark plugs and look for several things as inIs the Spark Plug covered in oilIs the spark Plug Rusty LookingChecking the Compression on all cylindersChecking cylinder Leakage on all cylindersPressure test the block with a radiator pressure testerCheck the color of the coolant/AntiFreeze see if it is brown or looks like chocolate milkYou can also test the Exhaust fumes from the tail pipe with a special testerBut if you do not want to perform all of these tests then the simplest thing that you can do to make sure all of the cooling ststems work properly.1)Remove the thermostat and put it in hot water and visually inspect to see if it opens if it does it works fine2) This is going to sound stupid but it works turn your heater on and watch your temp gauge it will rise for a little bit but then the guage will go back down to a lower temp. because you are heating up the coolant witch will heat the thermostat and cause it to open and allow flow of coolant3) Visually inspect radiator for leaks rust spots cracks and repair as needed4) Inspect Hoses Replace as needed5) Inspect water pump if leaking from pump replaceNow with all this being said check all connection points as in the radiator necks for cracks, breaks, softness check the water pump contact areas on the pump and block same goes if the problem is a head gasket if replacing but check for burrows, chips, frays, cracks, rust, any imperfection that will not allow the gasket to seat properlyAnother diagnosis is check to see if any previous repairs in these areas might be the cause as in look for spots where silicone and RTV are visible if so you will need a new radiator and the block will most likely need to flushed.Also one neglected area is the freeze plugs they might be rusted and leaking coolant replace as needed.I hope this information will help you in your repairs.
IS CODE for transformer oil?
Refer to:International Electrotechnical Commission IEC 836"Specifications for silicone liquid for electrical purposes" (Silicone Fluid Type T-1) andASTM D 4652 "Silicone Fluids for Electrical Insulation" specifications for repair or top-off of existing liquid-filled units.These standards cover both the physical and electrical properties of fluid suitable for dielectric applications.Also refer following:IS-335/1993 - Specification for uninhibited new insulating oils.IS-12463/1988 - Specification for inhibited mineral insulating oils.IEC -60296/2003 - Specification for unused mineral insulating oils for transformers and switchgear.
