Engineering - October 2007

in-pipe water flow - domestic - 22mm or 15mm copper is the main target, but if i can measure a 2" white waste pipe as well i will.

Don't like cutting pipe - if i could get a non-invasive clamp-on ultrasonic or hydromagnetic thingy doo dah I would

Accuracy and linearity not important - happy to calibrate with bucket and stopwatch. Best if not temperature sensitive.

Thanks!!

The reason I wanted to switch my major to mechanical engineering is because the undergraduate program in biomedical engineering taught me a bit of every subject: biology, engineering(mechanics, circuits......) but I didn't learn none of the subjects in depth. That is why I wanted to switch to mechanical engineering for graduate school to have an stronger engineering background to eventually work in the medical device field. I am just a concerned since I didn't take the undergraduate courses in mechanical engineering..& it seems to be a tuff major
Thank you in advance = )

...what inventions or discoveries could they help the people realise????

Personally I think it could be quite hard to show them new inventions. For instance, even steam power would necessitate the invention of new metal-working processes etc.

Any thoughts? Thanks.

The only infos that I got is my signal freq will be 8 - 45 Hz and need 20 M ohm preamp impedance. How do I determine the rest of the values, ie capacitance and resistors?

Hope someone could tell me what should I do 1st so that I could progress to next step.

Assume all public wire and wireless communication centers
broadcast public instruction to prepare for fifty meter wave
due in 6 hours on seashore nearest reader. Citizens are
notified public roadway transport, within the next 30 minutes, will likely slow due bumper-to-bumper........ (Static Sounds)...
the land under reader shudders a few seconds and electric
power fails. No cellular, no Fax, no Internet. Outside come
the first raised voices of panic.

Can reader reach terrain or large structure higher than 50 meters sufficient to resist the crush of wreckage such wave will carry? Name a safe destination, how one expects to reach it.....................or has reader different agenda?

If H = height, B = area of bottom face, M = area of cross section halfway up, and T = area of top face, then the volume formula V = (H/6)(B + 4M + T) works for a variety of solids, such as a cone, a box, a fustrum, a pyramid, even a sphere or ellipsoid. When does it work or does not work? What are the conditions necessary for it to work?

A pair of glasses is dropped from the top of a 32.0m high stadium. A pen is dropped 2.00s later. How high above the ground is the pen when the glasses hit the ground? (Disregard air resistance. A= -g= -9.81 m/s^2)

Please help with anything you can. thanks :)

A rock fell off a cliff and then a second rock fell 3.6s later and the initial velocity is 70.56m/s and the acceleration is 9.8m/s^2. I had to find the time that the rock fell to the ground and I got 5.2s but I think the time is wrong. Then to find the height of the cliff I used a distance formula and got 499m but that answer is wrong if anyone knows what I did wrong that would be very helpful.
