When was the first windmill ever created?
The first windmill was built in Persia in the 19th Century.
How thick does the wall need to be for a wall mounted toilet?
Pls let me know wether wall mounted water closet can be hunged on 4.5" partition wall, if yes now, if no, what is the ideal detail for wall mounted w.c.
* The Aswan high Dam is located on the Nile Riverright on the tip of Lake Nasser. Near the city of Aswan in Egypt.
With zero nose radius, the leading cutting corner of the HSS (high speed steel) cutting tool comes to a point. Cutting a surface with a pointy tool gives a non-smooth surface finish. Also, when cutting steel, tremendous pressures are generated at the tool tip. A tool tip that comes to a point is weak at the point and the tip can fracture easily. Unfortunately, this tool fracture makes an uncontrolled, new shape on the cutting edge that often wears really fast, and/or leaves a bad surface finish on the part. With a 2mm nose radius, instead of coming to a point, the cutting edge of the tool is rounded. One result is the same difference you would get in smoothing frosting on a cupcake with the tip of a knife (sharp tip) and smoothing the frosting with the end of a spoon (rounded tip). The rounded tip gives a far smoother surface finish. Also, instead of all of the force being pressed against a sharp tip, the 2mm radius distributes force across a wider edge, making a far stronger tool tip that won't break down nearly as readily as a sharp tip would.
Why dont you have to use coolant while machining cast iron?
As far as i know, coolant is not required while machining cast iron because, carbon in cast iron is present in the form of graphite (which is a cooling agent - self cooling). Moreover the carbon content is high in cast iron.
It is a good low temp gas to replace R12. Also known as 401A is a blend of refrigerants (22-152A-124). It is a good low temp gas to replace R12. Also known as 401A is a blend of refrigerants (22-152A-124).
A digester feed pump forces water to a boiler. It works by transferring cool water to the boiler to be heated.
What is compressor head as it relates to discharge pressure?
the head doesnt effect the output pressure of a compressor package but the size of the piston and the amount of clearence and volume between the piston and head changes your output psi
What are the advantages and disadvantages of Howe bridges?
The advantages of truss bridges is that it is economical, light, strong and uses short timbers. Greater strength with less material. Greater span (the distance between end points) than what most single beams. Easier to repair and maintain. Disadvantage can be wasted material if not designed properly. There can be no force members that do nothing for the structure.
What are the challenges of a greenfield project?
photogrammetry is a remote seasoning technology which determine the geometrical property of object are determine from a photographic image.i.e X,Y,Z coordinate.
What is the use of resistance box?
The use of a resistance box or a "Decade Box" is to help calibrate instruments used to measure electrical values such as Voltage, Current, and Resistance. Without them you would not have a known value of resistance to use as a set point.
What is the tachometer princibal?
THERE ARE TWO TYPES OF TACHOMETER. 1.D.C. TACHOMETER 2.A.C. TACHOMETER ALSO DIGITAL TACHOMETERS CAN BE CONSTRUCTED using various principles..... D.C. TACHOMETER its construction is very similar to a D.c. generator. it works on the principle of generation of emf wen a rotating conductor cuts the magnetic flux......when magnetic flux is constant then the emf produce is directly proportional to the speed of the armature that is coupled to the shaft of motor. A.C. tachometer its construction is similar to a two phase servo motor.... and works conversly of it....
12 volts only refers to the voltage, to be able to say anything about charge time you also need to know the capacity rating in amp hours of the batteries. Assuming lead-acid batteries the charger needs to go to > 14.4 V and then a proportional amount of amps as compared to the capacity rating of the batteries. A rough approximation is that batteries needs to be charged with about 1.4 times their amp rating. An 1 Ah battery would need 2 hours on a 0.7 amp charger for instance.
Yes, when designing something out of wood, it is very important to think about what it will be used for. You would want to make sure that it will hold up and do whatever job it is suppose to do.
yes
It means to rub your genitals against someone else's.... through your clothes though.
It's a valve that can open an hydraulic circuit befor the water inside freeze.
Difference between Black mild steel and bright mild steel?
from what i can gather, which isn't alot:
Cold Rolled Steel Strip is produced, as the term suggests by the further rolling of strip produced by the hot strip mills.Prior to cold rolling, the mill scale has to be removed, normally by the Pickling Process which uses mechanical manipulation (around small diameter rolls) and acid to dissolve the surface scale. The surface is then washed to remove the acid and a light oil added to prevent rusting.
Mild steel sheet is manufactured generally in two grades, cold rolled and hot rolled.
Hot rolled mild steel sheet is the initial product produced by the steel mill as a downstream process prior to further processing such as cold rolling.
Hot rolled mild steel sheet has a mill scale which is usually black in colour. Hence the common name Black Mild Steel Sheet. Black mild steel sheet is commonly used in fabrication shops, it is more economical than cold rolled mild steel sheet.
Black mild steel sheet will usually require more preparation work prior to any finishing system being applied.
Cold rolling is done to:
Reduce the thickness
Improve the surface finish
Improve the thickness tolerances
To offer a range of "tempers"As a preparation for surface coating
