ive got a pressure vs enthalpy graph which is based on the data for refrigerant 141b. If I've got a given pressure, and i want to find the enthalpy at that pressure how do i know where to stop when going along horizontally from a given pressure value?

I've just finished reading Einstein's Biography by Walter Isaacson. There is a pasage that got me thinking about the way Einstein observed the universe and his distaste for quantum mechanics. Einstein is famous for declaring that God dose not play dice, basically what he was saying is that, even...

Hi all, I am confused of how to find the “TOTAL TOOTH-TO-TOOTH SPACING AND PROFILE ERRORS e”. My Professor want me to determine the ERRORS of a Spur Gear with gear diameter d1 = 420 mm and pinion diameter d2 = 65 mm and a gear module m = 8 and the AGMA Quality is No. 10. When I see the...

I don't know how to describe this properly in a few words, hence the awkward thread title. I used to own this particular program which is able to decipher words in picture files to actual text which can then be copied to MS word or other word processors. It doesn't require a scanner but it...

Im a physics graduate, well nearly, graduating in 4 weeks time, and I get the feeling I don't know as much maths as I should. The most taxing things I've ever been taught within the course are operators, like the Hamiltonian, or div and curl of vector functions. I don't really know where to go...

So how do these work? Do you go up to a professor and request his assistance for independent study, after which point this whole deal is made official and you're credited for it? Thanks in advance.

Homework Statement These are some problems I need to solve. Do not solve them for me. I ask two things from you: 1) Explain what the question is asking from me, as I'm a little unclear on this. 2) Using a completely unrelated example, or whichever not-doing-it-for-me method you wish, give a...

I don't adhere to any religion nor have I been conviced there is a God. However I have recently decided that in order to better understand human history and current world affairs it would be very benefical to read the major holy books. My GF is currently reading the Bible and I am about 100...

I would like to read the original works of mathematicians and physicists. I am in the second year of maths & physics. I was wondering if this would be any good for me. Also, how would I go about finding their works? It's not as though the originals are published, it's mostly second hand stuff...

Does a physics reading course make a good impression on an undergraduate transcript? If given the choice between taking a reading course in an interesting subject and taking the same course as a regular class the following year, what would you do?

A certain pendulum clock that works perfectly on Earth is taken to the moon, where g = 1.62 m/s^2. Acceleration of gravity is 9.81 m/s^2 on Earth. THe clock is started at 12:00:00 AM and runs for 22 h. What will be the reading for the hours on the moon? answer in h T = 1 second g = 9.81...

I'm currently reading four textbooks in topology at the same time. When I read one topic, I don't move on to the next topic until I've read the same topic from the other books first. This may seem weird and a waste of time but I've noticed some following benefits: 1) Different authors give...

Anyone into detective novels? I've read a few of Henning Mankell's Kurt Wallander novels over a few years. I think they're pretty good.

Hello, I am writing a c program to read in data from a created file. This program has to calculate how many words, vowels and sentences from the text and use it to calculate a reading score. The score aspect is an easy part to program. I have made many attempts at writing this program and...

An elevator is at rest with a bag hanging from a spring scale. My question is Which force gives the scale reading? The mg (the weight of the bag) downward or the force exerted by the scale on the bag Fn gives the scale reading? thanks.

For the past months or so I've been having increasing difficulty to read words correctly; a word appears like another and I process it as so. Only upon a second lecture do I realize that I wasn't reading the word(s) right. I am curious because, like I insinuated, this difficulty has been...

Good day. I have recently become very interested in magnetic stripes; how they store data, how the data is read etc. They are something we use every day in our lives but what few people fully understand, and as a result, there is little documentation avaiable (from what I can find) that goes...

Can anyone provide me with insights on limits? Like L' Hospital rule (don't know whether spelt right), and product rule such as lim_{x\rightarrow\a} [f(x)g(x)] = lim_{x\rightarrow\a} f(x) \cdot lim_{x\rightarrow\a} g(x) should lim_{x\rightarrow\a} f(x) and lim_{x\rightarrow\a} g(x)...

Is it possible for the mind to comprehend so much information that it barely has time to recognize? Can some people really read 10 novels a week or is this unreal? Are only moderately above average speeds possible? - Jake

Hi I am reading the book "Introduction to logic and the methodology of deductive sciences" and I'm doing my best on understandig it and so far so good, but I ran to the example of the book: " for any number x, if x=0 or y not equal to 0, then there exists a number z such that x=y.z" I just want...

Hey guys, I was wondering if anyone knows of an open source solution for reading in a black and white image and converting it to text (preferably in a text file)? I've tried Google, but I could only find online generators. Thanks.

Sorry to bother you all with a trivial question. I'm a Belgian teacher and I'm struggling because I don't know how to read a formula in English. How do you pronounce the apostrophe in for example v'. In French we say 'prime'Can anyone help?

When solving a problem, the last thing you want to do is look at the solution. When you're trying to prove a theorem, axiom or whatever, is looking at a proof something that would impede your learning? To me it seems that the answer is yes. Looking at a proof removes the thinking process so...

Does reading or studying while listening to music improve or worsen your mental process?

Happened to come across this qn: Noise from receiver is measured by rms voltmeter with bandwidth 100khz, and voltmeter reads 2mV. what will be the reading for multimeter set to read dc voltage and bandwidth of 10khz? My ans is 10/100 x 2 = 0.2mV. cos smaller bandwidth reduced by a factor...

Which is more strenuous on human eyes? Because i do plenty a lot of both of them. If i learn that one is less strenuous than the other, i wil probably start spending more time doing that instead. Btw, i have an LCD monitor, which I've heard is better than a regular monitor, but it kind of just...

Any suggestion on how to improve your reading fluency with proofs of theorems? It's frustrating to spend over 1 hour to read a proof of a theorem that is under 1 page long (or not understanding the proof altogether). Even when every subtopic within a proof is already known, I find that...

Hi, I have a text file with 3 columns (latitude, longitude, & station name) and 51 rows. Using fscanf I am able to read the first row of the file but not the whole file. Any ideas of how to read to the end of a text file that contains both numbers and letters? This is what I have...

Behold Halliday's Question and Halliday's answers: The only force acting on a 2.0 kg body as it moves along the x-axis varies as shown in Figure 7-41 (see attatchment). The velocity of the body at x = 0 is 4.0 m/s. (a) What is the kinetic energy of the body at x = 3.0 m? 12 J (b) At...

Sorry, this sounds like a silly but I grew up in the age of auto-ranging multimeters. Say you have a scale, 1 to 10 and you select your scale as 1 miliamp. I presume if the needle is at 7 then that means 7 miliamps and NOT (7/10) 0.7 miliamps?
