Some stream data have been collected from a process plant, and these are listed in Table P19.2. Assuming the minimum temperature difference between streams, \(\Delta T_{\min }=10^{\circ} \mathrm{C}\)

(a) calculate the data missing from Table P19.2;

(b) analyse this data to determine the minimum heat supplied from the hot utility, the minimum heat transferred to the cold utility, and the pinch temperatures;

(c) draw a schematic diagram of the heat transfer network.

\(\left[360 \mathrm{~kW} ; 280 \mathrm{~kW} ; 2.2 \mathrm{~kW} / \mathrm{K} ; 4.0 \mathrm{~kW} / \mathrm{K} ; 2.0 \mathrm{~kW} / \mathrm{K} ; Q_{\mathrm{H}_{\text {min }}}=60 \mathrm{~kW} ; Q_{\mathrm{C}_{\text {min }}}=160 \mathrm{~kW}\right.\);
\(\left.T_{\mathrm{C}_{\text {pinch }}}=140{ }^{\circ} \mathrm{C}\right]\)
