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 (5.78x10^2) 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 he in m with three significant figures.

QUESTION 3 A single-cylinder, 4-stroke, 3-liter gasoline engine operates at 646 rpm and a compression ratio of 9. The pressure and temperature at the intake are 101.0 kPa and 32 °C respectively. The fuel used has a heating value of 42,500 kJ/kg, the air-fuel ratio is 14, and 77.2 % mechanical efficiency. The length of the indicator card is 55.1 mm with an area of 503.7 mm² and the spring scale is 0.85 bar/mm, considering a volumetric efficiency of 93.6% and a 24% excess air. Determine Brake Heat Rate in kJ/kW-hr. Note: Use two (2) decimal places in your solution and answer.
