Problem 1.6 A heat exchanger is being designed as a component of a geothermal power system in which heat is transferred from the geothermal brine to a "clean" fluid in a closed-loop power cycle. The heat exchanger, a shell and tube type, consists of 100 galvanized iron tubes 2cm in diameter and 5 m long, connected in parallel. The temperature of the fluid is 200°C, the density is 860 kg'm', and the viscosity is 1.35×10* Nm'. The total mass-flow rate through the exchanger is 50 kg's. a) Calculate the pumping power required to operate the heat exchanger, neglecting entrance and outlet losses. b) After continued use, 2 mm of scale develops on the inside surfaces of the tubes. This scale has an equivalent roughness of 0.5 mm. Calculate the power required under these conditions.
