$85,000$ lb$/$h of amyl acetate $($n$-$pentyl acetate, C$7$ H$14$ O$2)$ will be cooled from $175$ F to $125$ F by heating a stream of amyl alcohol $($l$-$pentanol$)$ from $75$F to $120$F$.$ Inlet pressures are $45$ psia for the acetate and $50$ psia for the alcohol. A maximum pressure drop of $7$ psi is specified for each stream. Specific gravities are $0\mathrm{.}81$ for the alcohol and $0\mathrm{.}83$ for the acetate.

$($a$)$ Develop an initial configuration for a shell$-$and$-$tube heat exchanger to meet this ser vice.

$($b$)$ Perform the rating calculations for the initial configuration developed in part $($a$).$

$($c$)$ Based on the results of the rating calculations in part $($b$),$ specify what changes, if any,

should be made to the configuration of the heat exchanger for the next trial.

$($d$)$ Obtain a final design for the heat exchanger.
