Refer to the shell-and-tube heat exchanger shown in below Fig. Both tubes are standard steel tubes with 0.049- in wall thicknesses. The inside tube carries 4.75 gal/min of water at 95°C and the shell carries 30.0 gal/min of ethylene glycol at 25°C to carry heat away from the water. Compute the Reynolds number for the flow in both the tube and the shell.
