# Your choice of drafting software?

Out of all of the drafting software on the market today, what would be your preference? What software have you tried and hated?

Personally I enjoy using inventor.

So I'm a new graduate with a degree in mechanical engineering and am struggling a lot to find a job. I've been applying to any job I see that I'm qualified for and still haven't heard back from a single company. I don't know what Im doing wrong, I'm writing unique Cover letters and tayloring my resume to every job. Any tips or other methods that might help me? (I'm getting really tired of the job boards)

# Load flow analysis (ETAP). Voltage at bar is more than 100%

Load flow analysis (ETAP). Voltage at bar is more than 100%

I was going over ETAP load flow analysis and in one of the papers, I saw that one of the values for bus voltages is higher than 100%. Example: http://ift.tt/2aALb39 page 3.

I understand that this is magnitude of the voltage. Why is it higher than 100%? Thank you.

# Thermal and Fluids Systems Mechanical PE practice problem help

Thermal and Fluids Systems Mechanical PE practice problem help

An automotive air conditioning system based on r-134a operates between 250 psia and 40 psia. A pressure-enthalpy diagram for R-134A is presented. If 250 psia saturated liquid R134a is throttled to 40 psia, the change [btu/{lbm-R}] in entropy (Sfinal – Sinital) will be most nearly.

a.) -0.07 b.) 0.01 c.) 0.11 d.) 0.15

Ok so the answer is B (.008) rounding up to .01 but I can not figure out how they do this!! If you google a pressure enthalpy chart for 134a, the entropy is given in btu/lb F but it asks for the answer in R. How do you even read this chart regarding entropy?! I don't remember this from school…

What is something you’d rather have your own of?

I.e. like safety goggles, tool sets, something that you should have your own of instead of using the provided set?

# What are some problems in every day Civil Engineering field which can be (or should be) solved with the help of technology?

What are some problems in every day Civil Engineering field which can be (or should be) solved with the help of technology?

As the question states, I am doing a survey for my internship and I'd love to know from professionals and college students too what are some things you would want to be automated or made easier with the help of technology.

An example would be a simple app to keep track of construction project which can detect the critical path (CPM-PERT model) and help the project manager keep up with schedule, with daily reminders and checklist.

Do you guys have any suggestions or ideas that you'd like to share?
