How to work this problem?

I'll help you if your a student.

Pure Water has a s.g. of 1 at 4 degrees C and mass is 1 g/cu.cm

use that as a relationship

You need to find the density of your material. You know the density of water (see previous comment - he says "mass" but he means "density"), and you (should) know that specific gravity is the ratio of the density of your material to that of water.

The rest is simple math.

thank you,

Keeping in mind what was mentioned above, here is a link for a freeware conversion calculator that I have used:

You still need to have the basic knowledge of how to perform the operations; you just don't need to remember all of the conversion factors.

I have to agree with the last two posts and find them very relevant to the on going problem of students asking CR4 for answers. I believe all members of CR4 are willing to help students. However this should only go as far as to point them in the direction where they can learn how to work through the problem and arrive at the answer themselves. We do them no favours by simply giving the answer. The only way to learn and remember what you learn is to do the work yourself.

Won't any good physics or chemistry book give the relationship between specific gravity and density? Like I tell my students, exhaust your resources before you start ask questions. This is not because I want to be mean and unhelpful, but because it will help you to learn the concepts better.

Slow down, we are only assuming that flchik24 is a student.

So what say you, flchik24? give us alittle background.

When if I see someone strugging, whether it be and engineer, student or laymen, and not knowing flchik24 background, I'll atleast push them in the right direction. Sometimes a gentle push, sometimes not......

"Like I tell my students, exhaust your resources before you start ask questions."

This forum can be considered a resource.

Yes I do agree with you, if they are a student they have to learn how to research.

When I was a student, If I had access to a forum like this, I would use it, (abuse it),until a professional would drop a hint.

Because even when I was a student I look for the easiest way to solve problems without compromising my education.

I don't know specific gravity from any other kind - I found the answer with a quick google.

Now I'll file that bit away for future use.

me too, good research.

10-4 Phoenix. As a teacher, I often have students ask before they think (or even look at the book or lecture notes in front of them) and this is a resource. I will go a little easier next time.

flchik, did you come up with a solution?

Also, I realized a typo in my last post. Please forgive my lack of attention to detail.

Not only student, most people are getting lazy. They'll rather ask the question in forum that do a Google search.

Many people only concentrate on the answer and not the skill needed to get the answer.

Our education only reward correct answer, not the effort spend on getting one. Student don't need to understand what they've learn, just need to memorize everything.

This is going off on a somewhat different direction,

I had an engineer who I managed, came from Michigan Tech so no question about his educational credentials. I had to do sizing program for shell and tube heat exchangers, (I felt that it was too complex for the designers and engineers I managed) they were young and\or had associates degree and were not interested.

He thought he could do it, and kept on nagging me, (I was also only giving it about 10% and putting it off also because of the difficulty and schedule), saying that he had that in school and was pretty good at it. I tried telling him it's not all out of the book with formula's, you actually had to get the program to work and do it correctly.

He made a slanted comment to me about I should not be in the position and that he could easily do it my job that is, so I gave the project to him, as well as some pointers, direction and references. And took over his workload

(even though he pissed me off the ingrate was out of school for almost a year and no one would hire him, except me because I saw some potential in him and there was)

Well he worked on it for weeks, and I asked for updates, when I asked to actually show me where he was, he said he couldn't do it because he was too busy?

I said give me what you have, well the only thing he had was that he had copied every possible formula out of all of my thermals books, (he didn't even have one, he didn't think it would be necessary to keep it after he graduated)

I look at it, threw most of the unneeded stuff out, which what was left is basically what I initially gave him, and had a unrefined working program done within the week

Your right, they only concentrate on the answer. And have been a manager or a teacher for that matter "which is part of managing", patience is a necessity.

What good is it to pass a test out of a book, when put into the real world where chaos is prevalent, with very little resources, the greenhorns do not realize that experience is priceless. And that knowledge is only a tool.

geez, you must of touch a nerve......

I find this is a recurring theme here at CR4.

I have been trying to develop a way to reward the process in my classes. I borrow a system that my physics teacher in high school used. The correct answer gets only one point. Each line of work in the process correctly done is worth one point. For high school this makes most physics problems worth around 5 points. A student could earn a B if they miss all of the problems but work them correctly.

Probably the fatal flaw in education is "social promotion" and a very low standard. When a kid can pass all of high school math without a good understanding of the material, the system breaks....Aaauuuurgh! I'm getting on my soap box.....I wish the system could be fixed, but it is way too political for any effective changes to be made on the large scale.

It sure makes a career in engineering very tempting...

My apologies for being off topic if anyone considers this off topic.

Thats is so corrrect, My math prof. in college, a student made a comment about grading on the bell curve, he shut him down so much as defending his position is that math you either knew or did'nt, its the only universal language.

The type of guy, is if he felt you were'nt paying attention, he would through an eraser at you, and explained the parabola path. He had everybody's attention.

But I knowest that when he was grading, If you had what he called the pattern down and felt you reconized it, but you error when that you missed a "-" sign he gave you credit for that.

"My apologies for being off topic if anyone considers this off topic."

And the definition of a forum is?
