Ethylene glycol flowing at a rate of 4.00 kg/s (Cp = 2.650 kJ/kg-°C) is cooled from 100°C to 60°C in 1-1 shell-and- tube heat exchanger. On the shell side, water flowing at 2.50 kg/s is used as the cooling fluid entering the heat exchanger at 27°C. The overall heat transfer coefficient is 1500 W/m2-°C and the pipe diameter is 2.09-cm. Compute for the tube length of this 1-1 shell-and-tube heat exchanger if 40 tubes are used. If the same heat transfer is intended for a 1-2 shell-and-tube heat exchanger, what will be its length? Calculate the following: 1-1 shell-and-tube heat exchanger q (kW or kJ/s) = Told.out = ATm = A = L = 1-2 shell-and-tube heat exchanger F = A = L =

4. Ethylene glycol flowing at a rate of 4.00 kg/s (Cp = 2.650 kJ/kg-°C) is cooled from 100°C to 60°C in 1-1 shell-and-
tube heat exchanger. On the shell side, water flowing at 2.50 kg/s is used as the cooling fluid entering the heat
exchanger at 27°C. The overall heat transfer coefficient is 1500 W/m2.°C and the pipe diameter is 2.09-cm.
Compute for the tube length of this 1-1 shell-and-tube heat exchanger if 40 tubes are used. If the same heat transfer
is intended for a 1-2 shell-and-tube heat exchanger, what will be its length?
Calculate the following:

q (kW or kJ/s) =
Tooldout =
ATm =
A =
L =
