Thermodynamics

Answer 2

For this I have to study Thermodynamics for you.. :)

Answer 3

thans :D

Answer 4

What thans?? And I am not going to study that... :P

Answer 5

@jim_thompson5910 good at thermodynamics?

Answer 6

Answer 7

Can you help me to him?? Whom to whom??

Answer 8

to jim :)

Answer 9

I did not study this subject when there was time.. :) Now there is time but again no mood of studying it.. :P

Answer 10

if I remember correctly you should be using \[q + (h_{in} +0.5c^2_{in}) – (h_{out}+0.5c^2_{out}) =0\]
where:
\(q\)=heat transferred per unit mass
\(h_{in}\)= specific enthalpy of inlet fluid
\(h_{out}\)= specific enthalpy of outlet fluid
\(c_{in}\)= velocity of inlet fluid
\(c_{out}\)= velocity of outlet fluid

Answer 11

and then sir?

Answer 12

\[\rho_{in}*c_{in}*A_{in}=\rho_{out}*c_{out}*A_{out}\\p=\rho R T\]
And you can reorganize the 1st i posted to this: \[q + (h_{in} - h_{out}) + 0.5(c^2_{in} – c^2_{out}) =0\]

Answer 13

\(A\)= section area
\(ρ\)=density
\(p\)=pressure
\(R\)=specific gas constant
\(T\)=temperature
