A shell-and-tube heat exchanger uses hot oil at 100-C to heat air. The oil makes six tube passes and the air makes one shell pass. It requires 120 kg/min of air are to be heated from 20 to 80-C. The specific heat of the oil is 2.10 kJ/kg. C, and its flow rate is 180 kg/min. Calculate the total required heat transfer in kW.

Heat Exchangers

Heat exchangers are the types of equipment that are primarily employed to transfer the thermal energy from one fluid to another, provided that one of the fluids should be at a higher thermal energy content than the other fluid.

Heat Exchanger

The heat exchanger is a combination of two words ''Heat'' and ''Exchanger''. It is a mechanical device that is used to exchange heat energy between two fluids.

Solution 1: Ergonomic Assessment and Improvement. An ergonomic assessment of Paula's workstation could identify areas where adjustments could be made to reduce strain on her wrists. This could include adjusting the height of the workstation, providing wrist supports, or changing the design of the tools she uses. The strength of this solution is that it directly addresses the physical strain causing Paula's discomfort. However, the weakness is that it may require investment in new equipment or tools, and the effectiveness will depend on the specific changes made. Solution 2: Job Rotation. Paula could be rotated between different tasks more frequently, reducing the amount of time she spends on tasks that strain her wrists. This could also include training other workers to perform the welding and gaging operations, allowing for more flexibility in task assignments. The strength of this solution is that it reduces the repetitive strain on Paula's wrists. The weakness is that it requires…
