- Water flowing in a long, aluminum lube is to be heated by air flowing perpendicular to the exterior of the tube. The ID of the tube is 1.85 cm, and its OD is 2.3 cm. The mass flow rate of the water through the tube is 0.65kg/s, and the temperature of the water in the lube averages 30C. The free-stream velocity and ambient temperature of the air are 10m/sand120C, respectively. Estimate the overall heat transfer coefficient for the heat exchanger using appropriate correlations from previous chapters. State all your assumptions.arrow_forward10.1 In a heat exchanger, as shown in the accompanying figure, air flows over brass tubes of 1.8-cm 1D and 2.1-cm OD containing steam. The convection heat transfer coefficients on the air and steam sides of the tubes are , respectively. Calculate the overall heal transfer coefficient for the heal exchanger (a) based on the inner tube area and (b) based on the outer tube area.arrow_forwardWater enters at 110 ℃ at a rate of 2 kg/s in a double-pipe parallel flow heat exchanger to heat a chemical whose inlet temperature is 20 ℃ and at a rate of 3 kg/s. The overall heat transfer coefficient of the heat exchanger is 1200 W/m2. ℃. The heat transfer surface area of the heat exchanger is 7.6 m2. What is the actual heat transfer rate of the heat exchanger? The specific heats of the water and chemical are given to be 4.18 and 1.8 kJ/kg.℃, respectively.

- In a parallel flow heat exchanger, with a cooler at 40 °C at a flow of 2 kg / h, hot water at 1 kg / h is cooled from 90 ° C to 60 ° C. The total heat transfer coefficient is 1000 W / m2K. Cph = Cpc = 4182 J / kgK. According to this; b) Determine the required space for the counterflow heat exchanger case.arrow_forwardConsider a liquid (Cp = 2.2 kJ /kg·K) is cooled at a rate of 12 kg/min from 150°C to 40°C in the tube side ofa double-pipe counterflow heat exchanger. Water (Cp = 4.18 kJ /kg·K) enters the heat exchanger at 10°C ata rate of 9 kg/h. The outside diameter of the inner tube is 2.5 cm, and its length is 6.0 m. Calculate the overallheat transfer coefficient. (Answer: U = 2.31 kW/m2·K)arrow_forward
