What is difference between ASME B16 & ASME B16.5 Flange

what the neccecities of shear test of brass & mild steel

Most commonly used is argon, but Helium can be used as well.

A static load is the mechanical force applied to an object as a result of both gravity's push and the weight of the object. It can be calculated by averaging out the two numbers.

The angle between chord line and turbine axial direction ( also known as setting angle)

Galvanic corrosion occurs when the two meet (especially when water is present) - use a barrier lubricant (Tefgel or anti-seize)

or plate the screws with Nickel/Teflon or Cadmium.

Astm a36. Its rot rolled steel with nearly matching with astm a36.

Power is supplied to the governor from the engine's output shaft by a belt or chain connected to the lower belt wheel. The governor is connected to a throttle valve that regulates the flow of working fluid supplying the prime mover. As the speed of the prime mover increases, the central spindle of the governor rotates at a faster rate and the kinetic energy of the balls increases. This allows the two masses on lever arms to move outwards and upwards against gravity. If the motion goes far enough, this motion causes the lever arms to pull down on a thrust bearing, which moves a beam linkage, which reduces the aperture of a throttle valve. The rate of working-fluid entering the cylinder is thus reduced and the speed of the prime mover is controlled, preventing over-speeding.

In the field of oil/gas drilling, it refers to hydraulic horsepower per square inch.

Tension = Module x deformation

Deformation= 2,51x10^-3 = 0,25%

Gauge in plastic sheeting is 100 000th of an inch. So 60 gauge should be 0.0006 inches or 0.015mm

Heating a metal decreases the tensile strength and increases ductility

A Closed loop system basically will have a feedback which enables the rectification of the error in the main process,whereas it is not possible in an open loop system

La norma o estándar ASTM A234 es una especificación para los accesorios para tubos de acero que incluyen materiales de carbono y acero aleado para servicios de media y alta temperatura.

La materia prima fuente de los accesorios de tubería de acero ASTM A234 WPB puede ser de tubería de acero, como ASTM A106 Gr.B y C.

Any pipe having pressure greater than 3.5kg/cm2 or having a size more than 254cm & is connected to steam generating circuit is known as IBR pipe & the rest are non-IBR pipe

becoz loaded truck has got more weight than the empty truck.....so becoz of which loaded truck has got more friction in tyres compared to empty truck...this may the reason why loaded truck starts slow than the empty truck

Most material being welded to 2205 including itself, should be welded with 2209 filler wire.

pirani guage can measure upto 10^-3 torr pressure

but

penning guage can measure beyond this

The principle stress is a maximum tension stress in a body where shear stress is zero and it acts on the principle plane. If a body is under both tension and shear then the principle stress is higher than the initial tension stress. You can calculate this and find the principle plane angle using Mohr Circle analysis or equations.

It is E*=( (1 - 'nu'12)/E1 + (1 - 'nu'22)/E2 )-1

It is used to describe a contact between two materials (the subscripts 1 and 2 corresponding each to one material).

E is the Young's modulus of the material and 'nu' is its Poisson ratio.

The difference between static load testing and dynamic load testing is that with static load testing a certain percentage of a product is tested against a group of specifications. During dynamic testing each individual product is tested against a group of standards based on previous tests.
