What is the number 40 stand for in 4140 steel?

The first two digits indicates a Chromium-Molybdenum alloy steel the last two digits indicates carbon content roughly 0.4 percent.

Are Lanthanide and actinide elements are transition metals?

Yes, lanthanide and Actinides are transition elements and they are specifically called inner transition elements.

What are the application of Schmitt trigger?

The application of Schmitt Trigger is as follows:

1.squaring circuit

2.sine-to-square comparater

3.amplitude comparater

4. as flip flops

What does a fusible link do within an oil installation?

Fusible link is installed on the hydralic line entering the actuator of the Blowdown valve. The frangible element (fusible link) will melt when exposed to a fire and cause an automatic blowdown of the exposed part of the system.

What does mcc stand for?

One description for mcc is motor control center. It is an electrical panel or cubicle which houses the one electrical incoming feeder several outgoing power feeders.

What is proximitor?

A proximitor is an electronic device that generates a radio frequency (RF) signal using an oscillator circuit. It also processes the RF signal to extract usable data using a demodulator circuit. A proximitor is often used in conjunction with a proximity probe to measure the displacement of a target surface.

What are the advantages of slotted waveguide antenna?

It uses Squint Phenomena. Target abd clutter will be hit by two beams seperately.

By this radar echoes will be added up whereas clutter which has Radar Cross Section Fluctuations will average. By this desired targets will be obtained with reduced fluctuations.

What is the principle of the operation of UltraSonic sensor?

The principle of operation of any known sonic sensor (the human ear, for example) is detection of air vibration by measurement of its sensitive membrane oscillation frequency.

What do you see as the short term business priorities in your current position as a process plant chief operator?

As a process fuels plant engineer my short business priorities:are:

continuous improvement in proces plants to ensure sustainability of the plants

Maintaining production capacity at 60% now to ensure the availability of petroleum products

re-stream Linear Akly Benzene plant and Lubes process plants to provide kero and touelene

Explain the steps in fabrication of monolithic ic?

this process involves following major steps... 1. Wafer preparation 2. Epitaxial growth 3. Oxidisation 4. Photolithographic process 5. Isolation diffusion 6. Base and emitter diffusion 7. Pre-ohmic etch 8. Metallisation 9. circuit probing 10. Scribing and separating into chips 11. Mounting and packing 12. Encapsulation (NOTE;- These are the processes involved for monolithic ic's. Detailed information can be found on internet.)

How solenoid valve works?

A soleniod is a device that produces mechanical motion by electrical induction. They are a coil of wire with either a plunger which is drawn into the coil or a plate that is drawn to a metal core. Most small water valves (like for an icemaker) have a metal plunger which is attached to a valve seat. When off, a spring holds the plunger down closing the valve. When on, the coil draws the plunger up and water escapes from the now uncovered hole to the outlet. Larger valves (like sprinkler valves) contain a small valve described above as a trigger device. They contain a diaphragm that seals the main valve and is held shut by water pressure on the diaphragm. When the trigger valve is opened, it releases the pressure and a light spring pushes the valve open, letting the water through. When the trigger valve closes, the cavity on the non-valve side of the diaphragm refills with water, closing the valve.

Design of earthing mesh in substation?

The mesh size in the earthing design for substation can be various size depend on the area. For area that does not contain equipment, we could increase the mesh size because there is no equipment to cause touch potential. But if the area is at the corner of the substation, the mesh size should be smaller because to limit the step potential.

What is paraffin paper used for?

paraffin papaer was used to line butter tubs.

What is the power consumption Kw of an industrial dehumidifier and air mover?

Dehumidifiers: between 1.05kw and up to 5kw for the big ones. Standard for those owned by restoration companies is 2.25kw.

Air movers: between 0.45kw and up to about 0.9kw. Standard is 0.55kw.

This is for the portable equipment, by the way. I don't know about the equipment that gets hard-wired into buildings.

What are positive consequences?

  • the crime rates go down.
  • the police taser a person and they don't die.
  • Positive consequences , are results of actions that come out for the better.

What causes radial thrust in a centrifugal pump?

When a centrifugal pump operates at its best efficiency point (BEP), the flow angles match with the impeller vane angles. At the BEP, the flow velocity in the volute is uniform around the volute (i.e., there is not acceleration of the fluid in the volute). Therefore, the pressure around the volute is uniform. The uniform pressure around the circumference results in a net zero radial force on the impeller (or the shaft). Note this is theoretical. In practice even at BEP, there is a small radial load because the pressure is not uniform.

If the pump is operated away from the BEP, the flow velocities in the volute are non-uniform which results in a non-uniform pressure field and a net radial load (can be obtained by integrating the pressure around the circumference of the volute or the impeller).

Is mild steel a rare metal or is it easily found?

some people consider it easy because they are miners, but otherwise it usually is rare
