How many miles per gallon does a 1995 buick century gets?
My 95 Century station wagon gets 22-25 mpg in city driving and up to 29mpg on the highway.
What is brake horsepower in hvac systems?
Brake horsepower is the hvac motor horsepower before the motor hp is dropped due to a load. Indicated, gross and SAE are other ways to rate horsepower.
What major errors were the results of faulty measurement?
So far, no one has identified any major errors that were the results of faulty measurement.
Two common misconceptions are actually errors of a different sort -- the Mars Climate Orbiter and the Hubble Space Telescope. The Mars Climate Orbiter was lost due to an inadequately documented computer program. The program produced estimated total thruster impulse. The results were thought to be in Newtons but actually were in pounds-force. This led do incorrect trajectory estimates. The trajectory was thought to be safely above the planet for Mars orbit insertion, but it was much lower. The spacecraft flew through the atmosphere during orbit insertion, causing the spacecraft to be destroyed by aeroheating.
A lesson that could have been learned there was that the English system of measurements must be expunged from the face of the earth (and the rest of the solar system). But it wasn't. NASA still uses a mish-mashes of mixed units. However, there are much bigger lessons to be learned here that apply to all walks of life.
* Communication between team members is essential. * Don't assume you know something -- verify * Have all interfaces documented and agreed to by all team members * A simulation of the pieces does not equal the whole * A test of the pieces does not equal the whole * Expect the unexpected and have recovery options
Hubble's problems were due to an incorrectly assembled optical instrument that was used to grind the mirror. Then the same instrument was used to verify that the mirror had been correctly ground.
Why is a true-length line always parallel to an adjacent reference-plane line?
You can see all the points equidistant
What is the stone saw found in 1 Kings 7 verse 9?
According to various sources, including Smith's Bible Dictionary, saws such as those mentioned in 1 Kings 7:9 were usually comprised of bronze blades with a handle on each end attached with leather thongs. Two men would draw the saw back and forth between them to cut and trim the stone.

What are the miles per gallon for an RV?
i have a 30 foot rig with ford 460 engine and if I'm lucky i will pull 9 mpg.
What is the importance of mathematics in engineering?
Engineers need to calculate the exact number of bricks, cement, metal or other materials to be used in making the skycrapers or any other building so as to minimize the cost of buying the materials!
Assuming you're talking about university...in the US...Pre-engineering courses are those that ready you for sophamore and junior level engineering courses. For instance, calculus based physics, linear algebra, chemistry, statics, etc. This differ from courses a liberal arts major would take in the amount/level of math they require.
How would you identify all surfaces finishes on an engineering drawing?
By stating the general surface finish in a general note (often pre-printed in the format). Any different finishes in the body of the drawing are indicated by a 'tick' symbol with the relevant surface finish value in Micometres or Microinches above the horizontal line of the tick.
Can you still be a mechanical engineer even though you hate and suck at drafting and sketching?
Well, I have been one for 40 years and I also suck at drafting and sketches. But it does help to learn to read drawings. Also, to have a passion for engineering principles.
Do what you like and like what you do.

What is a primary benefit of setting up a VoIP system at a home?
Not sure if this is a whole question. Setting up a Residential based VoIP system will save your family extra money in the long run. From making calls to businesses, spouse, friends and family chatting for a long while can cost you money. If they are out of the country it will be even higher of a bill due to International calling rates adding up.
Take a minute set your bill side by side to a select Residential VoIP provider that would charge lower per month and see if it matches or is lower then your actual cost now.
With so many choices out there compare Residential Providers so you can get the best services for your hard earned dollar.
Can you buy dynomite in Alaska at the store?
No, you can not! That would be dangerous, and nobody would want to be in danger!
In road engineering, a clay substrate can cause problems with its propensity to swell when moist, and its plasticity. Clay particles may be bound to 'burnt lime' CaO, and this is often used as a soil stabilizer. This mixture is much more stable. There may well be companies that have trademarked the name.
What is the ranking on engineering levels?
Engineering levels are pretty simple: * Level 1 or Entry level or Graduate level * Level 2 or Engineer * Level 3 or Senior Engineer / Becoming a Chartered * Level 4 or Lead Engineer / Chartered Status + postgrad * Level 5 or Chief Engineer / Chartered Status + Masters Eng or Business or PHD Each step takes 2 - 4 years depending on the individual.
Describe Burger vector in fcc material?
Slip in FCC (face centered cubic) crystals occurs along the close packed plane. Specifically, the slip plane is of type {111}, and the direction is of type <110>. In the diagram, the specific plane and direction are (111) and [-110], respectively. Given the permutations of the slip plane types and direction types, FCC crystals have 12 slip systems. In the FCC lattice, the Burgers vector, b, can be calculated using the following equation:[1] : [1] Where a is the lattice constant of the unit cell. Unit Cell of an FCC material.
The malloc function is one of a group of memory allocation functions; malloc, calloc, realloc, and free. Specifically malloc (size) returns a pointer to a new memory block of at least size bytes, suitably aligned for optimum access for any basic type, or it returns a NULL if the request cannot be satisfied.
How glucose convert into fructose through enolization?
The aldehyde of glucose can tautomerize to an enol. The ketone in fructose can tautomerize to the same enol. This enol can return to either keto form under the conditions promoting tautomerization.
Can an isolating transformer have a center earth tap?
I suppose it could, but then it wouldn't be purely an isolation transformer. It would then be a isolation and either step up or step down transformer.
