Consider a pumping system used in a cooling water loop. Water is drawn from a tank, which maintains a height of 2 m of water. It then enters the pump and then passes through the process heat exchanger, where it is heated. The water is then cooled back to cooling water temperature using a chiller (another heat exchanger). Finally, water exits the chiller and is circulated back to the original tank, forming a closed loop. All equipment is at ground level. All pipe in the system is 2-inch schedule 40, commercial steel pipe. a. If the flowrate is 15 kg/s, determine the Fanning friction factor in the pipe using the Colebrook Equation. b. At a flowrate of 15 kg/s, the heat exchanger and chiller each have a pressure drop of 15 kPa. Estimate the equivalent length of each heat exchanger.
