10.23 In a one-shell pass, two-tube pass shell-and- tube heat exchanger, ethylene glycol flows in the tubes and water flows in the shell region. The inlet and outlet temperatures of the ethylene glycol are 110C and 45C, respectively, whereas the inlet and outlet temperatures of the water are 25C and 60C, respectively. Using the LMTD method, calculate the overall heat-transfer coef- ficient for a surface area of 14 m and a heat transfer of 175 kW
