Figure shows a heat exchanger designed to cool 5250 kg/h of an ethyl alcohol solution (Cp = 3810 J/kg. °C) from 66 °C to 39 °C.Water (Cp = 4200 J/kg. °C) at 10 °C is pumped at 4750 kg/h to cool the solution. The tube side fluid flows in a circular pipe with an outside diameter of 25 mm. The overall heat transfer coefficient is (6.84x10^2) W/(m².°C). Find the tube length 'L' for one pass of a two-pass parallel flow double-pipe heat exchanger as shown in Figure. Answer should be in m with three significant figures.

QUESTION 7 A local brand of water heater has offered a counterflow concentric tube heat exchanger, consisting of thin walled copper drains with a diameter D; = 50 mm. Waste water from the shower enters the heat exchanger at Thi= 38 °C while fresh water enters the room at Te,j= 10 °C. The waste water flows down the vertical drain wall in a thin, falling film and providing h, = 10 kW/m²·K. i. If the annular gap is d = 10 mm, the heat exchanger length is L = 1 m, and the water flow rate is m = 10 kg/min, determine the heat transfer rate and outlet temperature of the warmed fresh water. ii. If a helical spring is installed in an annular gap so the fresh water is forced to flow a spiral path from the inlet to the fresh water outlet, resulting in he = 9050 W/m²-K, determine the heat transfer rate and outlet temperature of the fresh water. iii. Based on the result from Q5(b), calculate the daily saving if 15,000 guests each take 10 minutes shower per day and cost of water heating is…
