+//HEAT EXCHANGER
+//Oil flows in the tube side and is cooled from 280 F to 140 F
+//Therefore,

+t1=280; //Unit:fahrenheit
+//On the shell side,water is heated from 85 F to 115 F

+T2=115; //Unit:fahrenheit

+R=(T1-T2)/(t2-t1);
+//From the figure,

+LMTD=((t1-T2)-(t2-T1))/log((t1-T2)/(t2-T1)); //LMTD=Log mean temperature difference //Unit:fahrenheit
