Prime examples of funding is tollways.

I appreciate your side note at the end in taking your friendship into account instead of a simple and cold monetary decision. I also appreciate how you list common mistakes. I took a test for mechanical engineering for the city of San Francisco and that test is similar to the EIT/FE test. I haven't got my results yet but I know I struggled with the engineering economics part. Your videos fill that hole in my education.

lol, ummm 36=33 does not simplify down to 18=15

I'm a roofer. And ran into the subject of engineering economics. I was trying to learn accounting but you are a blessing. So much simpler. Thank you

Thanks for putting these out. I find them very helpful.

incomplete solution, and also answer is wrong supposed to be 243.75

with all due respect, your math is wrong at the end of the problem.

Would'nt the radiator on a car closed? The coolant stays in the car and doesn't leave, the same way a fridge is a closed system. Furthermore any research I do online leads me to the answer of a radiator being a closed system.

why you not using the 100?

where did you get the 1/2 from inside the integral in the second example?!

Sir is this playlist is completed

If there is anyone only checking the answer without listening, it is converting mass fractions to mole fractions.

Hi. This was quite helpful, particularly the part about comparing unequal lives, just like is done for PW. I could have missed that! Thanks. However, my previous understanding was that the alternative with the higher FW is usually selected. You seem to think otherwise for this particular example. My guess is that you would still select the one with the higher FW if the initial investments are reasonably close, right?

This is tricky. A radiator, when combined with the engine is a closed system. The coolant circulates between the engine and the radiator without ever exchanging matter (assuming normal operating conditions if the pressure relief valve is not activated). You could say the "refrigerator compressor" were an open system if you separated the one component. The problem is further complicated with mass in and out of the refrigerator door if you are looking at the whole refrigerator as the system, as the diagram given does. Is it typical for diagrams like this to be given with the problem or is that an explanatory addition on your part?

You are the best. You made it so easy to understand. Keep up the good work. Again thank you.

Thank you!

How do we know to use F/a column?

Thanks for the video! I'm looking at University of Maryland to learn more about engineering economics. Anybody have any information on their program? Is "Cash Flow" the usual beginning point in any engineering economics lessons?

i learn too much <3

i want more

you have more>?

i love this video i learn to much <3

The step between expanding the equation to the "simplifying and solving" step makes zero sense without an explanation of what you did

Good video, but this is a problem that realistically only takes 10 seconds. Just look at Mg being +2, then each H atom has to be -1 to balance it.

do mercury and water also have the same characteristics in an "unspecified" area? you arent in standard atmospheric conditions so wtf

another trap I fell into is that I considered Simple Interest to solve this problem. The interest in this problem is the Compound Interest.

In deciding which is better alternative, is the cost that you're talking about, is it in the overall cost of each alternative or the first cost of each alternative?

Thank you

I don't think your solution is correct.

thanks for sharing your knowledge ， that is really helpful ！！！

*This is what I did:* *-$45,000(F/P,12%,6) -$12,000(F/A,12%,6) +$10000* *Using the compound interest table we get answer as -$176,210.* *So this means the project is not feasible as its giving a loss.*

um. I think there's math wrong here. 3.8^2 = 14.44... so you get a slightly different answer in the end...

what happen to the four inside the quadratic how did we get rid of that.

why when doing the first triangle you used cos and then sin and then during the second triangle you used cos twice?

I just woke up at 3pm and got a exam tomorrow morning. Glad I found this because I can't mug up to even pass

Great video! Thanks for sharing !

*shitty content*

It's very helpful for me. Great analysis.

Thank you so much for the simple explanation

Is this video blurry to everyone else after the first 30 seconds?

thanks for the lessons <3

fuk the writing. cant read!

Need better hand writing. This was hard to read.

video starts at 3:44

Hey my man. Thank you. You help.

Very confused re: the column heading switch at 10:58. Correct me if I'm wrong, but the negative z should have been used to look up the R(z) value, and then just subtract that from the F(z) value that you got from the positive z. This solution was overcomplicated. Too much filler commentary.

Some pls help solve this A company is proposing a new equipment at 36,000. And he feels he will reduce labour and attract high price for his products at 6,800 per year over a period of 8 years. At the end of the 8 years the salvage for the equipment is 3,000. If the opportunity cost is 10%, calculate the benefit cost ratio

Great video though. But I'm not certain where the 3 came from, 4% gotten but the 3 how come about it
