In simple terms its a Joule

yes

Suction lift is only negative. Suction head is positive or negative.

Suction head is the distance between the surface of the liquid being pumped and the centerline of the pump. It can be positive or negative, and it can be affected by pressure or vacuum on the surface of the fluid. A negative suction head is also called suction lift.

Example 1: A D/A under 15 psig is set 20 feet above the feed pump the effective suction head is 54 feet. (15 psig is equivalent to 34 feet of water).

Example 2: A Condenser hotwell under 28 inches of vacuum (Hg) is set 16 feet above the suction of a propeller pump. The effective suction head (lift) is -15 feet.* (28"Hg = - 31 feet of water)

Example 3: A sump pump is set 4 feet below the surface of the well. The effective suction head is 4 feet.

*Note: Suction lift is only effective to a maximum of 21 feet, and 15 feet for hot water depending on temperature and pump slip.

you have to order from PEO (pay for the papers)

Buckling Load: It is the highest load at which the column will buckle.

Crippling Load: It is the max load beyond that load, it cant use further it becpomes disable to use.

The buckling Load < The Crippling Load

Safety load= Crippling Load/ Factor of safety

a- However most metals and many other solids have unit cell structures described as body center cubic (bcc), face cantered cubic (fcc) or Hexagonal Close Packed (hcp).

in level trigger mode, the input signal is sampled when the clock signal is either high or low whereas in edge trigger mode the input signal is sampled at rising or at the falling edge.

lever triggering is sensitive to glitches whereas edge trigger is non sensitive..

example: latch for level trigger and flip-flop for edge trigger

An idler gear is a gear which connects two other gears so they will turn in the same direction. :)

Well, interesting question. We use the usual, scientific method, so we can find what our project will taste and look like. And we also use chemistry because some foods,well, don't go together.

Labrynth seal clearances depend up the diameter of the rotating shaft, bearing clearance & temperature of the lubricating medium. As ageneral thumb rule the clearance must be 0.03 mm per 1" dia of shaft.

The disadvantages of using a shaper machine are s many. There are higher chances of injury that may cut deep into the skin.

the relay used to protect the generator/motor from overload currents. And to protect insulation of the stator windings.

There are many types of transmitters. Thesimplest is the Amplitude Modulated (AM) transmitter. This is an oscillator that cycles at a predetermined frequency. This oscillator puts out a level of energy that is varied by the sounds that you desire to transmit. This variance is done from 100% of the signal to 0%. The output then is two frequencies combined one at the stations frequency and one at the frequency of the sound transmitted. The receiver throws away the transmission frequency and amplifies the frequency of the sound.

Bottom line is you only hear the sound stuck into the transmitter.

F.M. is the same as AM but instead of varying power, we vary the frequency with the desire sounds we want to hear. The receiver sees that variance and converts that to sound.

Phase shift, DSB, SSB and the others are merely more complex variances to these basics.

Sure why not its the same as welding it to a straight piece of pipe

The load force is applying a force to move or hold an object that has weight.

It's called hardboard, it is basically super cardboard.

1. mainly surface grinding machines, for processing flat surfaces

2. To improve the roughness of the processing surface

3. grinding away a few wires to facilitate assembly

If you are interested in grinding machines, you can go to VIDO's official website to check, VIDO's grinding machines are of high quality and are the choice of the public.

Which of them travel faster - light or sound waves?

Light waves travel in vacuum with the speed of light c = 299792458 m/s or 983571056 ft/s.

Sound waves travel at 20°C (68°F) with the speed of sound c = 343 m/s or 1125.33 ft/s.

So light travels 874,030 times faster than sound.

Don't forget that sound needs necessarily air as a medium.

Light does not need a medium; vacuum is O

A dc generator is a machine which works on the principle of electro magnetic induction $it converts the mechanical energy into electrical energy.
