Consider a concentric tube heat exchanger with an area of 50 m2 operating under the following conditions:
Hot fluid Cold fluidHeat capacity rate, kW/K 6 3Inlet temperature, oC 60 30Outlet temperature, oC - 54
a. Determine the outlet temperature of the hot fluid.b. Is the heat exchanger operating in counterflow or parallel flow, or can't you tell from the available information?c. Calculate the overall heat transfer coefficient.d. Calculate the effectiveness of this exchanger.
Wind turbines are becoming more and more common as a method of energy production, wind turbines by their very nature are dynamic and are subject to and create their own internal and external kinematics and kinetics.
Air enters a 0.6 m diameter fan at 16 deg C, 101 kPa, and is discharged at 18 deg C, 105 kPa, with a volumetric flow rate of 0.35 m^3/s.
A 0.4 W cylindrical electronic component with a diameter of 0.3 cm and length 1.8 cm is mounted horizontally on a circuit board. To cool the component air is flowing across the board at a velocity of 150 m/min. If the air temperature is T∞= 45°C, ..
