no the water isn't boiling...Ive changed my method...which yields a better result... I'm heating up an object to a known temp and submersing it into the liquid and using that to find the Sc
I have a project due tomorrow and i need Help ... Calorimeter Experiment !
Homework Statement
My groups is terrible and is basically refusing to do any work---that's the real problem
My (other) problem is this:
I have a piece of copper that I am using as a calorimeter, I'm placing it inside...
Homework Statement
I'm trying to derive the \epsilon - NTU Expression for a double-pipe counter flow heat exchanger. I know what I need to do the only problem I am having is:
I don't know how to algebraically go from
ln( \frac{\Delta T2}{\Delta T1} ) = -UA ( \frac{1}{Ch} + \frac{1}{Cc} )...
okay so I'm home now and I've tried what was suggested but, I still don't get the right ans...:
510/1.75=8.30/(pi/4)*d^2
I used the reciprocals and got 1.75/510=(pi/4)*d^2/8.30 ... reduced and I got
sqr root (4*8.30*1.75/pi510)=d ans:.5982 the book ans is 6.02... where did I go wrong?
mechanics of matericals ... algebra question
I'm currently in Mechanics of Materials and I have reduced my problem to something similar to: 510/7.6=8.25/((pi/4)*d^2)
how do I solve for d? I have been given the answer (from the back of the book) but i don't remember how to solve for d...by...
simple math...just not for me

okay so I've tried several other things and I still can't calculate entropy production ...
I tried
-entropy production=m1(cp*ln(T3/T1)-R*ln(P3/P1)+m2(cp*ln(T3/T2)-R*ln(P3/P2)
but I don't get the answer my prof gave ... and even if I did how would I use my 'knowns' to calculate work?
