working of Centrifugal compressor

 Centrifugal compressor


In a multistage centrifugal compressor with intercooler, air  enters the first stage compressor casing  and passes into the eye or centre of the first stage impeller.


The rotation of the impeller imparts a high velocity to the air as it moves  radially outward into the diffuser or intercooler area where its temperature is reduced.

The air  is then directed into the eye of the second stage impeller where more compressions takes place and similarly to each stage of the machine. 

multistage-centrifugal air compressors are generally used for handling large air volumes at pressures up to 150 PSI and higher .

centrifugal compressors are often used for  instrument air services.multistage units can handle large air volumes at pressure to 150 psig and higher.

Wire wound strain gauge

Wirewound strain gauge There are two types of wirewound strain gauge  bonded and unbonded. Bonded strain gauge It consists of specimen surface  Gauge is directly bonded with the surface of the specimen  surface being tested. The thin layer of adhesive cement is also there this cement is  not only serve to transmit the strain from the specimen to the gauge wire but also act as an insulator. Depending upon the application the bonded strain gauge have various structure so we can use this structure as our application. Unbonded strain gauge These strain gauges are not directly bonded onto the surface of the structure under study. Hence they are termed as unbounded strain gauges. Description of the Unbonded Strain gauges: The arrangement of an unbonded strain gauges consists of the following. Two frames P and Q carrying rigidly fixed insulated pins as shown in diagram. these two frames can move relative with respect to each other and they are ...

Foil type strain gauge

Foil type strain gauge In Foil type strain gauge we use thin sheets or foils of 5 micro metre thick. by photo etching or masked vacuum deposition process , based on our requirement or application we can shaped the strain gauge. The end turns are made fat so as to reduce the contribution from the transverse strain which is a superiors input. Metal Foil Strain Gauge The arrangement consists of the following; The metal foil of 0.02mm thick is produced using the printed circuit technique. This metal foil is produced on one side of the plastic backing. Leads are soldered to the metal foil for electrically connecting the strain gauge to a measuring instrument (wheat stone bridge). Operations of Metal foil Strain gauge With the help of an adhesive material, the strain gauge is pasted/bonded on the structure under study. Now the structure is subjected to a force (tensile or compressive). Due to the force, the structure will change the dimension. As the strain gauge is bonded to the structure, ...

Do an ALP to compare two eight bit numbers NUM1 and NUM2 stored in external memory locations 8000h and 8001h respectively. Reflect your result as: If NUM1NUM2, SET MSB of location 2FH (bit address 7FH). If NUM1 = NUM2, then Clear both LSB & MSB of bit addressable memory location 2FH.
