No problem,
I was using Fouriers Law
q=kAdT/s
k = .25 for nylon
A= 60sqft for a wall
dT= 35deg F
s = .003"
This equation yields some insanely high transfer rates... I'm assuming that is MAXIMUM thermal transmitting capacity of the material if heat were constantly applied to one side of it...
Sorry, I wrote the question when I went to bed, and read your response when I woke up... needless to say I was very groggy.
I'm just trying to not have to differentiate through the layers of air, I know most equations are calc-based but as far as using calc, you don't have to :)
I'll ask...
Well I do love being called a liar right off the bat.
I'm mechanical engineering with a specialization in manufacturing, meaning while everyone else was taking heat transfer i was taking advanced cad/cam, welding, metal casting (our school has a foundry)
I know I need to "break it into...
Hello, I'm engineering a heat-pump for my senior project. My professor is out of town and these questions have been on my mind.
I'm trying to calculate ACTUAL heat loss through the tent walls and ceiling.
I'm using a tent 10ft x 5ft x 6ft.
I'm trying to heat it with approx. 750 btus/hr...
this is only a quick response but the angle is at 90 deg
the shape is to be neglected
the change in momentum does change as it is integrated from 50 to 0 but i am still unfamiliar w/ which vars to integrate
The sled slows due to the resultant force associated with shooting water 90 deg from the horizontal.
The shape/angle aren't important as far as the class knows. Only knowing flow @ 180km/hr is important.
Homework Statement
This is extra credit, and the test has passed (no one got it), the prof said he'll still take efforts on it so here is my attempt.
A rocket sled is going down a test track at 180 km/hr (calculated to 50 m/s). It drops a snorkel into a trough of water. This diverts 30...
