The pH scale is a measurement system that indicates the concentration of Hydrogen ions also called Protons.
Where do you put gear oil on a 1998 suzuki sidekick?
Gear oil (80W90 or similar) is used in the transfer case and differentials.
What is passive safety system for nuclear reactor?
Passive means that something will happen on it's own, depending only on laws of physics, such as gravity or pressure differentials. In this type of system the emergency core cooling systems are not dependent on electric driven water pumps to move coolant water.
a change in the sound's frequency caused by the motion of the sound's source

What is the process of gear cutting in a horizontal milling machine?
The basic process of cutting gears on a horizontal milling machine:
- The operator makes sure the machine is off and leaves it off at this point. He also checks the coolant and oil levels and cleans the machine if necessary.
- The milling machine head is removed and the overarm is extended over the bed.
- A milling cutter (selected according to the profile of the gear tooth) is installed on the arbor and centered with spacing sleeves. It is then inserted into the spindle and fastened.
- An arbor support is slid into the overarm and over the arbor, then fastened.
- On the table of the milling machine, a dividing head is placed and fastened to the bed (to the left of the arbor and its chuck facing toward it). The billet (workpiece) to be cut into a gear is gripped in the chuck of the dividing head. The dividing head is locked.
- The operator makes sure no feed levers are engaged and the spindle is in neutral.
- The machine is switched on, started and warmed up.
- After the machine is ready it is stopped and the correct speed and feed for machining the gear is selected.
- Before starting the machine, the table is moved so the workpiece is below the cutter and the workpiece is centered to the cutter along its Y-Axis.
- The machine is started again and the operator touches the workpiece with the rotating cutter then zeroes the Z-Axis dial on the vertical feed crank.
- The table is moved to the left along its X-Axis so the workpiece clears the cutter and the table is lifted a few millimeters for the first cut.
- Coolant is turned on and the X-Axis feed is engaged towards the cutter enabling the cutting of the gear groove.
- When the groove is complete, the table is lowered and moved to the left again to clear the cutter, then lifted to the same amount as the last cut.
- The dividing head is indexed and rotated to the next groove position, locked, and the cutting process is repeated until all the grooves are cut. This process can be repeated several times depending on the depth and size of the gear grooves and only a fraction of a millimeter will be left for finishing.
- The operator will ensure the cutter is still sharp and in good condition before commencing with the finishing cuts.
- A pre-finishing cut is taken and the groove depth and profile is measured. If all is fine, the table is lifted to the final cut depth and the cutting process is repeated until the gear is finished.
- Once the gear is removed from the machine, the sharp edges are removed.
The above method is just a basic explanation of how the operation is achieved. Operating any machine tool without proper training is not recommended and could lead to serious injury!
How do you make a jet backpack?
you buy a rugrats backpack and fill it with gas in little waterbottles then you point them all down and light..then you should be flying....or you could get high with a backpack on
Difference between manual system and automated system in system analysis and design?
A manual system analysis require individuals to supply input directly into a system designed to simulate real life events. An automated system is controlled by technology to automatically supply input.
What is a reservoir engineer And what do they do?
A reservoir engineer simulates a model of a real oil field and thus determines basic parameters of the reservoir which helps as guidelines for a drilling engineer to drill a well on a particular location. Reservoir engineer has to analyse a well throughout it's life hence it also ties up with a production engineer to suggest him ways how to extract the oil lying underneath the formation. There are several other roles which a reservoir engineer plays and thus serves as one of the major pillars of the Petroleum Industry.
There are additives that can improve performance of an older engine, or clean a neglected one. Remember that a lack of performance is an indication of work that needs to be performed, a bottle of goo will not permanently solve any of your vehicles issues. You can, however slow down the break down of the oil you do buy with stabilizers, these work well, and always change the oil on schedule, sooner if possible, it is your cars life blood.
Research new technologies thoroughly before you buy. Make sure you know what is in the product. If they list a secret formula, but don't tell you what it is, be cautious. They may contain harmful chemicals, such as chlorine or detergents. Others may contain PTFEs and metals, which can show temporary improvements, but can ultimately clog filters and damage your engine. Check their MSDS, certifications and independent studies by accredited labs, with their company name clearly listed. Also be sure they have product liability insurance and a warranty. Most brand name oils contain oil additives in them already. Both oil companies and independent researchers are constantly researching new technologies to improve engine performance.
Does standard SQL allow built in functions to be used in a WHERE clause?
Yes.
Example: Select `Id`,`Name` From `Order` Where `OrderDate` = CURDATE() And `IsShipped` = False
What is the size of a lathe that measures 6in from the center of the spindle to the main bed?
A lathe that measures 6 inches from the center of the spindle to the closest part of the bed is considered a lathe with a 12 inch swing.
A frac tank is used to hold water, or a proppant, when a well is being fractured. The material is held in a frac tank and connected by a hose or pipeline to a pump that will flow it down the wellbore at a high pressure to push open the formation and the proppant is used to keep it open.
21,000-gallon tank, 500 Barrels, for on-site storage of fluids. Also known as: mobile storage tank, portable tank, VE Tank, Baker Tank, Rhino Tank, Rain-for-Rent Tank, E-Tank
Frac tank is basically a generic term for mobile steel storage tanks used to hold liquids. Typically used for fracing wells in the oil and gas industry, a frac tank may also be used to store any liquids like run-off water, diesel fuel, glycol, oils, waste products, etc. They are usually 21,000 gallon single wall steel tanks, but are also offered as double wall tanks by Gaurav Associates of India, AFC Tanks, VE Enterprises and Truck Center of Fort Worth Inc. These tanks have a single rear axle to be moved with a winch truck or tractor when empty. The major manufacturers of frac tanks are Gaurav Associates, AFC Tanks, VE Enterprises, Dragon, and Wichita. Alpha Tanks and VE Enterprises make heated Frac Tanks that may be used in cold climates where regular Frac Tanks freeze. Heated water also improves the effectiveness of the fracturing process.
How does pi have to do with engineering?
Basically Pi 3.14.... Etc. is the number that is used for circles. Should you want to build a building with a cirlce roof you'll need to find the circumference. Basically you multiply pi with the diameter and you get the circumference.
There is a lot more to it than that; pi turns up in many contexts which aren't about circles. One is Fourier series, used in problems ranging from the distribution of heat in physics to acoustics, image analysis, and in filters in circuits in electrical and computer engineering. The formulas for Fourier series involve pi.
I think you will find that pi turns up in every branch of engineering.
