magnetic moulding, is an innovative process in which an expendable model is used that is surrounded by metallic particles bonded together by the action of an induced magnetic field. Once the cast metal has solidified the magnetic field is interrupted so that he would collapses by itself, the part is recovered and the particles can be reused in the subsequent castings. The innovative process combines the advantages of the lost foam process and the permanent mould processes; it is environmentally friendly, cost competitive and suitable to produce high quality parts with very complex shapes with a large range of sizes and materials. The components produced do not need any parting lines and the metallurgical and mechanical properties obtained are better than those obtained in lost wax, lost foam and sand casting due to the fine grain structure obtained through the fast solidification phase derived from the use of the metallic particles that form the mould. The potential impact of the new foundry technology is therefore large as it will enable European sand casting and investment casting foundries to offer complex shaped parts with high metallurgical quality through a knowledge based foundry process. The concept on which the magnetic moulding is based was born in Europe together with the lost foam process concept. The maturity of the lost foam process and the results from the investigations in the magnetic moulding concept of the last years finally makes it possible now to approach the proposed project to develop the new foundry process up to the industrialisation stage. The two RTD performers in the group have experience in the lost foam process and one of them has already had the first positive experiences in the magnetic mould concept at lab scale.

to reduce frictional losses and increase lubrication

Near the objects to be welded.

Because the engine is placed on the carburetor body and the engine is warm. The carburetor should be in the metal to be melted.

A person can gain admission into Malaysian University by applying for entrance. The school will pick people who will be a goof fit for the college.

Ford Motor Company made cars more affordable starting in 1908 when Henry Ford started producing the Model T on and assembly line instead of them being hand built. In 1909 the Model T sold for $850 and by 1913 the price had dropped to $550. In 1915 it dropped again to $440 due to Ford perfecting the assembly line method of building the car. By the 1920s, the price had fallen to $260 because of increasing efficiencies of assembly line technique and volume.

Based o the torque required for easy opening/closing by human efforts.

multistage is used because the expansion of high pressure steam will be gradual and as a result the rotor wont vibrate.suppose we have only 1 stage of blades in a turbine, hence all the steam will expand in the given stage and the speed of the rotor will be in high range around 30,000m/s, which is very difficult to control and operate the turbine.

There are classes for students who can take precision machining. A company called Choice Precision Machine says there is not limitation of distance or job when it comes to shop manufacturing.

Water would not be a suitable working fluid for a refrigeration cycle, because its freezing temperature and boiling temperature are too high and too distant from each other.

In the evaporator and in the condensator, you need the working fluid to change its phase.

Also, it would cost a huge compressor to this cycle, because the difference of pressures between the freezing and the boiling points is too high (0ºC: 0.611 kPa; 100ºC: 101.325 kPa)

The term gauge design is exactly what it sounds like. It refers to how the gauges on certain equipment pieces are placed out and designed.

A cast iron tub is about 325lbs. steel is about 75lbs. Tap on tub if it sounds solid it is cast iron.

Fourth stage is usually terminal and inoperable. Radiation may slow the process.

Tensile strength is given in ksi. To get pounds you need to know the area. Pounds = strength x area. For example if the specimen is 100 ksi strength and area 1 sq inch, pounds = 100 x 1 = 100 kilopounds = 100000 pounds. f the specimen is 100 ksi strength and area 2 sq inch, pounds = 100 x 2 = 200 kilopounds = 200000 pounds. In any case strength in ksi is the same for a given material and that is why ksi is used.

The lead Engineer is the person with innovations from Mathematical models so that the Technologists can implement it.

procedures in testing hydrostatic pressure in fluid(water)

Rotary means going around, like in a Wankel. Reciprocating means going back and forth. like in a ordinary piston engine.

Yes!

Let us do some conversions first, then use the ideal gas law.

PV = nRT

1 Bar = 1.01325 atmospheres

80 Bar (1.01325 ATM/1 Bar) = 81.06 ATM

20 C = 293.15 K

new R = 0.08206 L*ATM/mol*K

(81.06 ATM)(100 L) = nI0.08206 L*ATM/mol*K)(293.15 K)

moles O2 = 337 moles O2 * 32 grams

= 10784 grams

The first screw press was invented by the Romans, sometime in the first century AD. The exact date and the inventor are not known.

I assume you mean a 4 x 2 square tube that is loaded in the direction of the 4 inch dimension; then it is stronger than a 4 inch channel with flange width of 2 inches loaded in the direction of the 4 inch dimension, because the square tube has more inertia
