For adiabatic operation and
when the work done by the stirrer can be neglected Equation
(9-12) can be written as |
|||
|
|
(9-13) | ||
where An
analytical solution relating X and T can be found for the
case of constant or mean heat capacity. Combining Equations (2-6)
and (9-13) yields |
|||
|
|
(9-15) | ||
| multiplying by dt, separating variables and integrating between the initial conditions, X = 0 and T =T0, and later conditions X =X and T =T, yields | |||
|
|
|||
| Taking the antilog, we have | |||
![]() |
|||
| solving for X yields | |||
![]() |
|||
| Then | |||
![]() |
(9-16) | ||
| This form is the same as the equation relating X and T derived for flow reactors. Rearranging yields | |||
