I know there's one floating arond for dynamics, was wondering if anyone had one for Fluids.

Failing that, anyone in Cassidy's section that has any clue how to do some of these homework2 problems?

I know what you mean man, I cant get this homework.

6/4/2006 5:19:18 PM

ive got the solutions for another textbook if you want some more sample problems

but since you are asking for solutions and not help i doubt thats what you want

6/4/2006 6:27:47 PM

Didn't a whole lot of people get kicked out of a dynamics class for cheating from the solution?

6/4/2006 7:42:06 PM

Actually I am indeed looking for more sample problems - that would be most excellent. Anything to explain it better than this sorry excuse for a textbook.

6/4/2006 7:48:28 PM

any specific questions?.... i might be able to help...

6/4/2006 8:40:03 PM

well ive got old sample problems, but they are 50mb
so i dont know the best way to send them to anyone

how do you get the mass flow in problem #6 when it give u the non-uniform velocity

6/4/2006 10:25:03 PM

Well that midterm sucked balls.

6/6/2006 9:07:26 PM

I am glad somebody else thought so, that thing was horrible

6/7/2006 10:01:52 AM

just post problems on here

6/7/2006 6:13:16 PM

I got his email with the first four problems for homework #3 - did he mention the rest of the problems in class? Can anyone post what the full assignment is?

6/9/2006 10:47:54 AM

Wow, never mind - his e-mail arrived literally three seconds after I posted.

Okay, the answers he provided for the first question must be wrong. Anyone else getting -1.405 kN for FRx?

V1 = 2 m/s
V2 = 15 m/s

P1,gage = 114.4 kPa

Do those intermediate results look correct? For the life of me I can't figure out what is missing...

Guess this is mostly directed at lumbeestud.

If you post the question on here we could help you out. Answers are not really doing anything

6/9/2006 7:17:58 PM

If you check back later in this message board...I think the topic was Gould MAE 308 there are solutions on there. Cassidy is working under Dr. Gould their homework should be pretty similar

A helicopter of mass 10,000 kg hovers. Its blades rotate at 400 rpm. The blades cause a 15-m diameter air mass to move downward at an average velocity proportional to the rpm of the blades (V = kw).

Determine the volumetric airflow rate downdraft that the helicopter generates.

The density of air is 1.8 kg/m3.

yeah i had that exact HW problem. I still have all my homeworks from his class last year and I guarantee he gives the same problems. Anyways the answers are:

(a) volumetric flowrate = 3832.94 m^3/s
required power input = 1064 kW

(b) required RPM = 632.5 RPM
required power input = 4200 kW

Hope that helps.

6/10/2006 6:47:24 PM

Thanks - actually he gave us the answers for this one - can't figure out the process.

6/10/2006 8:40:31 PM

Okay I just made a copy of that packet outside his office. I'll be studying tonight, Saturday daytime, and all of Sunday. If you get stuck on a problem, post which one and if I have time I'll post the solution. I would scan and post the entire thing, but it's 21 pages long, my scanner sucks, and I don't have the patience.

i wasn't able to make it to class today.... did i miss any important announcements about the exam?

6/23/2006 9:31:17 AM

8 or 9 problems.

Four or five of those problems will be short, not full calculations. Might be multiple choice.

The other four or five will be full homework/test quality questions.

8:00 am Monday.

Don't worry about fully solving Navier-Stokes equations, just be familiar with how they work.

6/23/2006 9:38:12 AM

thanks a ton!!!! good luck studying

6/23/2006 4:49:04 PM

...and we have escaped. If he grades that final like he graded my tests, I'm golden.
