What is weld log?

A weld log is a Quality Managment tool that acts as a database used to keep an ongoing record of welds made during construction fabrication type projects. The Weld log is used to record Important information recorded as "weld number" Welders Stencils", "Weld Procedure", "Weld Type" Material Type" "Project#" and any other important information to ensure the traceability and Quality Assurance of each welded junction during fabrication or repair activities. The best example can be found here: http://sites.google.com/site/masterweldtracker/


What kind of machines are most machines?

These days there are 4 main types of fax machines: 1) standalone fax machines - these are the "traditional" type of fax machine that sit on a counter 2) multifunction machines - these are fax combined with a printer, scanner, or copier. These can be a small countertop unit all the way up to the size of a big office photocopier 3) online fax services - this is a fax service that is hosted like an webmail inbox - it sends and receives faxes for you (often through your email) and you log into it like a webmail inbox. 4) enterprise fax servers - these are a version of online fax services but run through a large organizaiton's IT department.


What are the causes of High T5 in solar gas turbine engine?

Your question is a bit to vague to cover everything. You'd need to be specific about the running conditions. High T5 can be caused by overload of the unit as well as a variety of fault conditions. If the unit is running in T5 control mode (ie: full load) and experiences alarms or trips, it may be that T5 gain and integral values need to be adjusted to smooth out the over-shoot. Make sure that the fuel supply pressure to the unit is stable as the fuel system will have to counteract any changes in flow due to oscillations in supply pressure. This can introduce instability in the loop leading to high T5. If the unit is running below T5 in speed control (NGP) and suddenly trips on a very fast rise in T5, it's worth checking the speed probe and connections all the way back to the card. If there's a downward spike in the sensed speed due to loose connection or poor probe gap adjustment, the control system will react by putting in extra fuel to try to get back to the set-point, causing high T5 trip. This will very often be too fast to pick up on HMI or trigger log. There can also be problems with fuel valves that can cause poor temperature stability. Injector fouling is another possibility if your fuel quality is poor. Have a look at the T5 spread to see if they are all reading close to the same value. In very hot climates where the air inlet temperature go very high in the Summer months, you will hit the T5 control mode limit earlier than when the T1 air inlet temperatures are lower. Hope that this helps.


What instrument measures speed?

It depends what you are measuring the speed of.The best-known way to measure speed is to divide the distance travelled by the time taken. If a 20km trip takes 1 hour and 15 minutes (1.25 hours), then the speed is 20/1.25 = 16 km/h.In any vehicle with wheels (car, bicycle, train), the distance can be found by counting the turns of the wheel. The speedometer is calibrated to show the speed.A GPS calculates the distance travelled by measuring the distances between a series of points on the ground (The location of these points is established from satellite signals). Speed is then calculated from the time taken between each pair of points.In an aircraft, speed is measured by a small tube pointed forward, called a pitot tube. The higher the air pressure in this tube, the greater the speed shown by the airspeed indicator. The vertical speed indicatormeasures the difference in the outside air pressure, which decreases with altitude.In a boat the pitometer log operates on the same principle as an airspeed indicator, but with water instead of air.All of these methods measure the speed with which you are moving. What if you want to measure the speed of something else?A radar gun is used by police to catch speeders. It can also be used to tell the speed of a baseball pitch or a tennis serve. It works on the Doppler effect: the frequency of the reflected radio waves goes up with increasing speed. The distance to a galaxy is related to its red shift(also a result of the Doppler effect) which shows the speed with which the galaxy is moving away from us.The speed of a moving fluid can be measured by a propeller. An anemometer measures wind speed, and a velocimeter measures the speed of a stream.Then again, you might want to measure the download speed of your internet connection, or the velocity of circulation of money, or . . .

How do you get past the logs on the cliff in red dragon?

First, you wait for the first log to go backwards. then you jump to the middle floating rock. then you stand on it waiting for the second one to go backwards, then jump up until you see a rope. then you climb the rope and when your at the top, you jump left and hopefully youll land on a rock. then once you get the rope, another rope will be there. do the same thing with the first rope. then youll see cliffs. hop on them. then youll see a third log. it wont hit any thing so you dont have to jump on a rock. when it goes toward you, ( make sure your not too close to the log ) jump on it and run to the back of the log. then jump on the rocks until you see a cliff with a white toy lighthouse thingy jump and land on it, and go right.

When would you use a one system pulley?

I think you mean "a one pulley system." When you want to pull in the opposite direction you want the object to move. If you tow a log behind a vehicle you don't use one so the log follows the car. But, if you wanted to lift that log you would throw the rope over a tree branch or pulley to lift it into the air as you pull down, thus using your weight with gravity to help lift the log.However, by attaching the pulley to the tree branch, you don't gain any mechanical advantage other than using gravity with pulling down.If, on the other hand, you attach your one pulley to the log, attach one end of the rope to the tree branch, and lift up with the other end you do gain mechanical advantage with it requiring half the force of the previous example of pulling down. But, you are limited by working against gravity and you can only lift as high as you are standing.
