P31220 lab 1 mechanical energy and heat purpose: terminology “work” and “heat” represent energy that is in motion when we do work on a system, we increase its mechanical energy a pot of hot water has thermal energy enough detail so that you can write a detailed lab report professional scientists learn (usually the. Chapter 2 mechanical equivalence of heat 21 purpose the purpose of this lab is to demonstrate the equivalence between mechanical work and heat 22 introduction note: for this experiment, you will write a complete (formal) lab report and hand it in at the next meeting of your lab section this lab can not be your dropped grade for the semester. Cold is the absence of heat, hence in order to decrease a temperature, one removes heat, rather than adding cold in order to satisfy the second law of thermodynamics, some form of work must be performed to accomplish this. In this lab you will be looking at the conversion of mechanical energy into heat energy this is a simplified version of an experiment done by james joule and published in 1850.

The work ∆ w (mechanical energy) is the joule equivalent of heat or the mechanical energy equivalent of heat energy in si units, j =4186 joules/kilocalorie in this experiment a constant current i will be used to flow through a resistive heating joule equivalent of electrical energy. The mechanical equivalent of heat introduction this is the classic experiment, first performed in 1847 by james joule, which led to our modern view that mechanical work and. Experiment 6 ~ joule heating of a resistor introduction: value 4184 j/cal and is numerically equivalent to the specific heat capacity of water in this lab, show your work suppose that some liquid other than water were used in the calorimeter if the liquid had a.

  • The work done by gravity is w(x) = mf g(x-x0), where x0 is the flag position at the release calculate and record for each position the total mechanical energy of the system, kinetic energy plus potential energy in addition to the standard elements of a well written lab report described in the introduction to this manual, your report.
  • Sample lab report in the writing guidelines for engineering and science students: guidelines to help students of science and engineering make their writing more efficient for others to read and to make the process of writing more efficient for them to perform.

The work required to transfer heat from a cold reservoir to hot reservoir would result in a net increase in heat energy to the room, unless the back of the fridge was place outside the window the later scenario increases the atmospheric heat transfer from inside to the outside and resulting in the closed room decreasing in temperature. Me 3264 lab 3: cross-flow heat exchanger 1 me 3264: lab 3 department of mechanical engineering, university of connecticut cross-flow heat exchanger professor wilson k s chiu spring 2017 objectives the objectives of this experiment are: (a) understand and practice basic heat exchanger analysis methods. In your lab report 13 a heat engine introduction the engine converts some of the heat flowing into it from a hot water bath into the mechanical work done lifting the load it then dumps the remaining heat into an ice water bath the engine cycle consists of processes between the following four states. In the history of science, the mechanical equivalent of heat states that motion and heat are mutually interchangeable and that in every case, a given amount of work would generate the same amount of heat, provided the work done is totally converted to heat energy the mechanical equivalent of heat was a concept that had an important part in the development and acceptance of the conservation of.
