A single$-$effect evaporator generates a distillate product at a flow rate of $1$

$k\frac{g}{s}.$ The system operating temperatures are as follows:

The boiling temperature, $T_b,$ is $90C,$

The feed temperature, $T_f,$ is $85C.$

The steam temperature, $T_8,$ is $102C.$

Determine the heat transfer areas in the evaporator and the condenser, the

thermal performance ratio, the flow rates of feed seawater and reject brine,

and the flow rate of cooling seawater. Assume that the specific heat of

seawater is constant and equal to $4\mathrm{.}2k\frac{J}{k}gC.$

Chapter $2$ Single Effect Evaporation

Repeat problem $1$ and use the specific heat correlation given in appendix C

for seawater. Compare the results against those obtained in problem $1.$

Comparison should include the relative percentage difference of the two sets

of results.
