Hi David
What did you but for the ii) part of the question?
I was thinking it would be:
Q=UA(Tf−Ts)
where
U = overall heat transfer coefficient for the system (Wm^−2∘C^−1)
A = heat transfer area (m2).
Hey Jim
Thanks for the info, someone at work is very good at PID controllers also. The above solutions are correct.
I will mark this as solved now.
Thanks again
Homework Statement
(a) With the aid of a sketch explain how proportional action is produced
in a pneumatic controller whose output is 0.2 to 1.0 bar. Assume that
the controller is direct acting.
(b) Show, mathematically, that the output is dependent on the difference
between the measured and...
Hello everyone.
I am new to Physics Forums. I seem to be doing the same course studying as you all too. I am having difficulty on how you managed to get
t = -5 ln(4/10)
t = 2.55
I am coming out with
t = 4.58
Any help would be greatly appreciated.
Thanks
