Question 3 An industrial company recently installed a hot water system operates by hot geothermal water. The geothermal water (Cp = 4250 J/kg.ºC) at 95°C is to be used to heat fresh water (Cp = 4180 J/kg.°C) at 12°C at a rate of 1.2 kg/s in a double-pipe counter-flow heat exchanger. The heat transfer surface area is 25 m?, the overall heat transfer coefficient is 480 W/m2.°C, the effectiveness of the heat exchanger is desired to be 0.823, and the mass flow rate of geothermal water is larger than that of fresh water. The company assigned you to do the complete analysis on this hot water system. As an engineer, i. calculate mass flow rate of geothermal water (kg/s), ii. estimate the maximum rate of heat transfer (kW), ii. calculate the actual rate of heat transfer (kW), and iv. determine the outlet temperatures of both fluids.
1. A crossflow heat exchanger, one fluid mixed and one unmixed (oil in tubes and steam in shell), is used to heat an oil in the tubes (c = 1.9 kJ/kg°C) from 15°C to 85°C. Steam (5.2 kg/s, c = 1.86 kJ/kg°C) blows across the outside of the tube, enters at 130°C and leaves at 110°C. U. = 275 W/m²K. Calculate A. [10.84 m²]

Water is flowing at the rate of 1.13 kg/s in a 1-2 shell-and-tube heat exchanger, and is heated from 45°C to 85°C by an oil hav- ing a heat capacity of 1.95 kJ/kg K. The oil enters at 120°C and leaves at 85°C. Cal- culate the area of the exchanger if the overall heat-transfer coefficient is 300 W/m2. K

(b) How large must it be if, after some months, a fouling factor of 0.0015 m²K/W is expected to build up in the tubes but we still want to deliver ammonia at 30°C? (c) If we make it large enough to accommodate fouling, to what temperature will it cool the ammonia when it is new? (d) At what temperature does water leave the new, enlarged exchanger?
