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.

Case Study – The New Engineer Jeff was just hired by GSI, Inc. to be their Environmental and Safety Coordinator. This is Jeff's first position after completing his engineering degree. He had taken a course in safety engineering as part of his studies and felt confident that he could handle the job. Management at GSI, Inc. has assured him that they are committed to maintaining a safe workplace. They have never had an individual dedicated to this task full-time. They will implement his recommendations if he can justify them. As Jeff begins to get familiar with the operations, he spends considerable time on the production floor. He notices workers clean their tools before break with a liquid from an unmarked 55-gallon drum. They also use this liquid to clean residue from their skin. They use paper towels to dry their tools and hands, throw these towels in the trash, and head to the break room for a snack and/or smoke. In talking with the workers, Jeff learns of some of…
Show full work in handwritten format. Subject :Mechanical engineering Q:The flight path of a jet aircraft as it takes off is defined by the parametric equations x = 1.25 t2 and y = 0.03 t3, where t is the time after take-off, measured in seconds, and x and y are given in meters. If the plane starts to level off at t = 40 s, determine at this instant (a) the horizontal distance it is from the airport, (b) its altitude, and (c) its speed. Answer: 2000m,1920m and 175.3m/s respectively.

An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J). It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).
