The number of moles dumped into the river from the concentration at the measuring point by summing the amount of $$ \Delta{N} $$ between 20 and 50. $$ \int_{20}^{50} Q_{river}C(t)dt=777,60,000 moles $$ The center of the pulse is the mean residence time. $$ \frac{V}{Q}=35 $$ $$ Q=6000...

Residence time distribution- the time an entering particle spends in a system before it leaves. The residence time of molecules in a system is measured using tracers. The response for a system is recorded for some type of perturbation. Consider $$ A+B \rightarrow C $$ and suppose we want to...

TL;DR Summary: I have a problem designing an axial turbine, there is a lot I don't understand hey, how are you all doing, I am a chemical engineering student working on designing a geothermal power plant, weirdly I have been told that I must design an n-pentane turbine for our Plant, it's so...

hey , I bumped into this forum while searching for something and thought it was a great idea to stick around and surround myself with amazingly smart people, its my honor to join you guys and thank you for reading

The general balance equation is as follow: d[m{u+gz+v2/2)sys=(u+gz+v2/2)dmin-(u+gz+v2/2)dmout +dq+dw. I understand that I would take in consideration the cross sectional area as well as the mass flow rate. However I can't figure out what else to consider as if atm pressure should be considered...

I'd like to do some experiments with flames at different Equivalence Ratios - but I'm confused as to how I can find the Equivalence Ratio for different conditions. Wiki-article So the stoichiometric balance for Methane + Air is CH4 + 2(O2 + 3.76N2) -> CO2 + 2H2O + 7.52N2 Referencing equations...

Summary: Since I did not start out in calculus 1 in my first semester of college I have to take an extra semester in my four years to get my bachelor's degree in Chemical Engineering and Clemson offers a minor in Nuclear engineering which would just add 15 more credit hours to my overall degree...

Hello everyone. I am from Kolkata, India. This year I have cleared IIT-JEE and taken admission to the Indian Institute of Petroleum and Energy, Visakhapatnam Chemical Engineering which is under the mentorship of the Indian Institute of Technology, Kharagpur. Even though I had to pursue...

What are the differences between a degree in chemical engineering and a degree in chemical engineering technology. I think that the main difference is that someone who studied ChemE Technology has more knowledge in chemistry than someone with a ChemE degree. Salary wise, which one pays the best...

Hello Physics Forums, I have been struggling with this question for some time now and I'm not sure my method is correct - please see attached. Any help you can give to check I'm on the right lines would be very much appreciated! Cheers, C

I would very much appreciate anyone to cast their eye over my attempt at solving this problem which I've been struggling with the past few days. Many thanks in advance. Assuming that: energy input from open-type regenerative feed heater pump is negligible no energy is lost the heater pressure...

I have ~50% slurry mass in a reactor with (4 PBT + 4PBT) agitator. Agitator is rotating at 94 RPM. To analyze reaction mass we are sending two samples at a time from bottom of the reactor. There is significant analysis deviations in these two samples. I feel that the sample is not...

The assignment is to find the optimal operating temperature and maximum product concentration of reactant B, assuming a constant temperature across the PFR length. Please could someone help? thanks the reaction is a series reaction: A → B → C (liquid phase) Here is my current code which is...

Please could someone point me in the direction of an equation/ book I can use to obtain the convection coefficient for steam in a heating jacket. Steam is at 1 bar pressure. I think I need to use a dimensionless number. Thanks

I am trying to find an alternative tuning rule for use with the transfer function specified. Please could someone help by pointing me in the right direction, thanks. Process transfer function: ## \frac {27e^{-3s}} {30s+1} ## Also, am I right in thinking that this process transfer function is...

I have the Cp of Benzoyl peroxide (BPO) in gas form (454.39 J/molK). What approximation could I make to find the Cp of solid BPO as I cannot find this info online? thanks

Please can someone assist me as this particular question seems to have me completely confounded?

Summary:: Would it make sense for me to switch from physics to chemical engineering if I have no interest in most chemical engineering jobs? I’m currently a first-year physics major. Over time, I’ve come to the conclusion that my general interests lie in applied science rather than in pure...

In the chemical engineering text of Smith, VanNess, and Abbott, there is a section on partial molar volume. It states that Gibbs theorem applies to any partial molar property with the exception of volume. Why is volume different? In other words, when evaluating the partial molar volume of a...

So with our initial prototype for our anaerobic digester, we weren't able to sustain the right temperature inside the tanks. One idea we came up with is to use the heat from the compost bins that is only within 10-20 feet from our tanks. We plan to circulate the fluid inside the digestion tanks...

<Moderator's note: Moved from a homework forum.> Dear team, I wish to use CO2 to de-air a device by exploiting the physical properties of CO2 as a heavier, more dense gas to air and therefore displace air in a very thin tube that has a nozzle at the end where both air and CO2 can escape. I wish...

Hello, I am attempting to expand my physical understanding of some engineering principles I’ve learned during my first semester of ChemE. I am making a small plastic car that will be propelled with a weak fan. I am attempting something similar to a ChemE project car. Is there a way I can use a...

Homework Statement A double effect forward feed evaporator is to concentrate a 12.5% solution of a certain chemical compound "YZ". The feed is to be at and is to be 120 F of such an amount as to contain 6250 "YZ" per hour. Saturated steam is available at 250 F (29.7 psi ). The accepted value of...

I am curious about production amounts and prices for an annual period, for a few thousand commodity or common chemicals. I noticed a couple chemical intelligence services but they seem out of the price range for an amateur researcher. What kinds of sources are available to look further?

I am currently a Sophomore, studying chemical engineering at Drexel University. After college, I want to pursue a career in the downstream petroleum industry. However, I am unsure of what minor would help me get closer to reaching my goal. I have heard business and mathematics minors are great...

We most often witness the presentation of quantum dots in viles or containers which are excited via UV light. I am more interested in their electrical excitation. Could I simply take a sample of QDs from one of those viles and passing an electrical current through that sample excite the...
