This is being done as a project in class. The air flow rate was acquired by use of an anemometer. All the units were in GPM the bulk fluid properties were looked up. A typical anemometer reading from our experiment showed the inlet and outlet flow ranging from 1200-1600 GPM where the anemometer...

I am currently working on a project which requires a mass and energy balance on a fin/ fan heat exchanger. The problem I am running into is finding how to apply the fin efficiency to find out the amount of hea tbeing dissipated through the fins. The hot fluid is water and the cooling fluid is...

Now my question is in regards to part A since I now have the calculated work. How can I calculate the heat from the heat processor? It is not clear in the book on how to do that. I know the inlet condition as being steam that has been throttled to a pressure of 600kPa and that the outlet comes...

Yes I do have access to them. I just redid the work with those values and got the same answer as the VdP method as well. Thank you for leading me to the compressed water steam table! So the temperature had been lower than the saturation temperature meaning it was subcooled? Thank you again for...

Here are my calculations. The first attempt was with the assumption of the pump being isentropic. I knew that through inspection my answer had to be incorrect just from my calculated entropy value not falling between the data points. My second attempt was following an example in my textbook...

Our course book and my professor have taught me that a pump is isentropic. At least for these sections. Is it not? I have uploaded a PDF of the problem. It is Problem 2 part A regarding a Rankine cycle. I know I've made my own interpretations, but I was just going off what was taught from class.

Homework Statement A pump with inlet of saturated liquid at 600kPa has an exit stream of 10MPa calculate work Homework Equations Energy balance equation Entropy balance equation Linear interpolation Steam table The Attempt at a Solution My attempt at the solution was to calculate the entropy...

They have helped me in my approach thank you. The problem statement did not clarify if there was any change in the outlet stream so I proceeded to solve it with the same outlet pressure of 10 bars. It is also how my professor solved it. Dylan

First I'd like to thank you for your clarification and detailed response to the problem. To answer your question if I know how to determine the entropy from initial state to final state. I am pretty sure I would use the equation ΔS=∫(Cp/T)dT-Rln(P2/P1) I know that since the process doesn't...

Homework Statement A well-insulated tank of volume 6 m3 is divided into two equal volumes. The left part is initially filled with air at 100 C and 2 bar, and right side cell is initially empty. A valve connecting two cells will be opened so that gas will slowly pass from cell 1 to cell 2. The...

Homework Statement A steam turbine in a small electric power plant is designed to accept 4500 kg of steam at 60 bar and 500oC and exhaust the stem at 10 bar. Part C. In off-peak hours, the power output of the turbine in part a) (100% efficient) is decreased by adjusting a throttling valve...

This is what I was looking for thank you!

I am trying to use that PVδ=constant The book uses that to get the term of work into a term where the n factor can be used. Here is a picture of part of the solution I am referring to and it has the part in question highlighted My question is how are they coming to that answer for work...

Homework Statement One mole of an ideal gas is reversibly compressed from 1 bar to P2 bar that results in temperature increase from 400 K to 950 K. Calculate the heat transferred during the process and the final pressure, if the path followed by the gas can be given by PV1.55 = , and the molar...

Hello All, I am currently reading Introduction to Chemical Engineering Thermodynamics 7th Edition By Smith, Van Ness, Abbott. This very subject has come up within my book on pages 126 and 127 for those who have the text. In the subject of Sensible Heat Effects it outlines for a homogeneous...
