What does copper and tin make?
Tin and copper make bronze, with bits of coal to make brass. some may think it makes a solid bronze bar by playing runescape, alot of things in runescape are incorrect when it comes to the ores, smelting, and smithing
How can you pre-rust corten steel with muriatic acid?
Do not use dangerous HCl or hydrochloric acid (muriatic acid) and go with a mixture of sodium chloride (salt ) and distilled water. Spray a mist evenly over the previously sandblasted Corten for a numbers of days while letting the surface dry between coats until the desired surface is achieved. This can take days or weeks depending on your environment. i.e. the Sahara vs the Amazon. You will need to sandblast first. The key to excellent results is the prep: use fine sand or 80 mesh aluminum oxide for the sandblasting. Keep dry and immediately start the pickling or patination process to insure an evenly rusted protective surface that is aesthetically pleasing.
Best university for biomedical engineering?
The best university for Biomedical Engineering is Johns Hopkins University located in Baltimore, Maryland. If this is not a prime location, maybe the other nine will be more suitable? Check the source.

What are the different phases of combustion in a petrol engine?
1) Inlet, 2) Compression, 3) Ignition, 4) Exhaust. Otherwise known as; Suck, squeeze, bang, blow. 1) Fuel / air mixture is injected/drawn into chamber. 2) Mixture is compressed by piston. 3) Spark, and mixture burns, pushing piston down 4) Piston returning to top of cycle pushes out burnt exhaust gases.
What is the calorific value of sludge in waste water?
Basically,
calorific value of any sludge depends on its constitution. Since sludge is not defined composition wise, its accurate calorific value doesn't exist.
And another important factor which affects the calorific value is the end product that's generated out of sludge. eg if biogas is generated, then calorific value would be 22,000 kJ/Nm3 (http://www.currenta.com/pages/1577/life_2008_final_engl.pdf)
topic open for discussion!!
Gabions are bottomless baskets or metal frameworks filled with rocks, also known as panniers they are available in a variety of sizes they help solve erosion problems at low costs.
rotor is the moving/rotating part of a motor/generator
while stator is the stationary part.

How do you convert MMSCFD to M3h?
The conversion can be done simply by first converting MMSCFD into M3D i.e converting Millions of Standard Cubic Feet per Day(MMSCFD) into Standard Cubic meter per day (M3D)
1 MMSCFD = 28316.847 M3D
= 1179.869 M3h (however this is for a standard temp of 60oF)
What is the definition of energy management?
Energy management is the discipline and measures executed to achieve the minimum possible energy use and cost while meeting the true needs of the activities occurring within a facility. Actions intended to achieve this energy efficiency focus on reducing necessary end-use, increasing efficiency, reducing wasted energy, and finding superior energy alternatives.
Inconel materials are metal alloys which generally have a high content of nickel. They often contain varying amounts of chromium, molybdenum, and iron. The amount of each metal in an inconel, as in an metal alloy, varies by the specific alloy.
differentiate between indicating and integrating instruments
The resulting resistance of the parallel combination will be the resistance of the original wire divided by n squared.
Does rear impact cause front airbags to deploy?
2005 GMC Envoy hit on rear passenger lower side, minimal damage, barely visible to naked eye, but both front air bags deployed. Did the impact cause this?
Why petrol engine is not suitable for part load operations?
In case of Petrol engine power is controlled by Throttling. Now, at part load due to throttling the initial and final compression pressure decreases and dilution of the working mixture with residual gases thereby hindering a smooth prorogation of flame (undesirable phenomenon). This difficulty can be overcome by enriching the mixture (air-fuel ratio) at low loads which causes a wastage of fuel and also emission of pollutants.
Most practical envelope detectors use either half-wave or full-wave rectification of the signal to convert the AC audio input into a pulsed DC signal. Filtering is then used to smooth the final result. This filtering is rarely perfect and some "ripple" is likely to remain on the envelope follower output, particularly for low frequency inputs such as notes from a bass guitar. More filtering gives a smoother result, but decreases the responsiveness; thus, real-world designs must be optimized for the application.
An envelope detector is an electronic circuit that takes a high-frequency signal as input and provides an output which is the envelope of the original signal. The capacitor in the circuit stores up charge on the rising edge, and releases it slowly through the resistor when the signal falls. The diode in series rectifiesthe incoming signal, allowing current flow only when the positive input terminal is at a higher potential than the negative input terminal.
Source vest pocket book Dennison Handbook for Engineers?
Engineer's Vest Pocket Book by W.A. Thomas, originally printed in 1930... reprinted by Dennison... I went through a number of copies in the 60's until it went out of print. Not currently in print but used copies can be found. First edition recently sold on ebay for less than $10 but most places will ask considerably more. Try FetchBook or AddAll and expect to pay at least $20.
What is the temperature of oil in the Alaska Pipeline?
the max temp of oil in the pipeline is 145 Fahrenheit

SAE4137 or 34CrMoS4 according to the metric 2009 Misumi, Mechanical Components for Assembly Automation Catalog (www.misumiusa.com), Technical Data section, page 2866.
cf means cubic foot in engineering. But when it comes to English, cf means confer, which is actually a Latin word. Confer means consult in English.
If 360 has red rings and power brick glows yellow?
if it is 2 red rings it meens it is overheating so unplug it and wait 15-20 minuates then plug it back in. if it is 3 red rings aka red rind of death (rrod) there are many methods to fixing it but the one i found most affective is the quitip method look it up on youtube. or the towel method which is only a temporary fix. If it is 4 red rings that meens you just need to unplug all the cords wait a minuate then plug them back in and turn it on. i hope this helps!
Where might an acoustical engineer work?
Acoustical engineers are often employed as consultants to architects to advise on details of building elements: walls, floors, windows. In that capacity, they must be conversant in architectural as well as mechanical issues, since heating and air-conditioning (mechanical) equipment is often the source of noise that the architect may be concerned about. An acoustical consultant would be an essential member of a design team for an auditorium, sound stage or recording studio.
Acoustical engineers are also employed in manufacturing situations, both as part of the design team to advise on how to design products for low noise (or better sound...) as well as in the capacity of hygienic professional to address hazardous noise areas of factories, etc.
This question refers to the communication between a network and networked devices. Feedback between a computer and the network occurs through 'pings,' when each acknowledge each other intermittently.
