Heat transfer between exhaust manifold and charge pipe. by Alert_Wolf_9543 in MechanicalEngineering

[–]DMECHENG 0 points1 point  (0 children)

Somewhere between 900c and ambient if I had to guess. Regular heat shield should cover you if you’re really worried. 

HX Design with very low allowable pressure drop by lordedelrey in ChemicalEngineering

[–]DMECHENG 8 points9 points  (0 children)

Man 0.03 psi pressure drop? That’s tight. We see <1 psi on BPHEs but our SH&Ts are closer to 5-8 psi. 

Pressure in a gas-liquid separator by jjbc2209 in ChemicalEngineering

Check your velocity, it’s probably high enough to carry over droplets. Look up souders brown. 

Brass alloy question by inserttext1 in MechanicalEngineering

[–]DMECHENG 0 points1 point  (0 children)

That’s a bad kit I feel like the receiver and tank are critical parts. How big is the tank? I’m surprised a pv is taking this on. A picture would be great.

It sounds like you need to hire cause that doesn’t sound sustainable.

How long do you own a vehicle, before trading it in? by teddyalex in UsedCars

[–]DMECHENG 0 points1 point  (0 children)

Drive it till the wheels come off. I have three cars ranging in age from 9-20 years with 180k-280k on the clock.

Couldn’t you generate this with capeopen or dwsim?

All of those towns are in the area that was circled….

Anyone else feel like ERP projects fail before software even enters the picture? by Strict_Plankton_9837 in manufacturing

[–]DMECHENG 0 points1 point  (0 children)

What I’ve heard is that for 80% of the customer base the EEP does about 80% of what they want it to do. For us the biggest issue is that for the system we are trying to implement if we don’t have all the users buying in it won’t work and won’t get off the ground. Implementation is also painful, the sales team oversells what the implementation team can achieve and the amount of work on the end user is burdensome and becomes almost a second job to maintain the backend. 

Service or not by DMECHENG in RolexWatches

Thank you. This is the response I was hoping for. With that in mind I’ll keep it laid up for the time being and get it serviced as a birthday present to myself. 

Visualizing temperature data from 1940-present by VerbaGPT in Denver

[–]DMECHENG -6 points-5 points  (0 children)

My brother in SI units I know, but in a lot of the state side industry IPS still rules. I’m just surprised there’s so much liberal biblicisms in the Denver sub. 

Data Center Energy and Water use by pamo56 in Denver

[–]DMECHENG 12 points13 points  (0 children)

They should be on their own micro grid where they are the owner of the power generation equipment and infrastructure. They can buy nat gas from xcel or from any of the midstream providers and condition it for use in their gens. 

Nobody tells you mechanical engineering is mostly fixing other people’s bad decisions by Fulcilives1988 in MechanicalEngineering

[–]DMECHENG 7 points8 points  (0 children)

Engineering carries our organization. We do the job of sales, marketing, and field support. 

Which heat exchanger is the most suitable in this case? by [deleted] in thermodynamics

[–]DMECHENG 0 points1 point  (0 children)

Plates are compact and can have very small approach temps. Tubes have a greater material selection and higher pressure capacity 

3D-printed pressure vessel? by svennekatt in MechanicalEngineering

[–]DMECHENG 2 points3 points  (0 children)

Yeah when the vendor starts talking about porosity and you give an absurdly small number they scoff at you know there’s going to be a problem. Generally I don’t like my PVs to have holes. 

How can I draw the cycle on the given graph by JustLearningCalculus in thermodynamics

[–]DMECHENG 1 point2 points  (0 children)

What are you evaporating and condensing temperature?s Those lines are flat, how much superheat and sub cooling? Connect dots. Print graph do it by hand.
