    Ti NSpire cx - 2 questions, last equation, and touch pad?

    Hm the ctrl+c and ctrl+v combo works for the equations I tried, but it's a little tedious. I had tried scrolling up and clicking to bring the equation back down, but I specifically was unable to get this to do anything with summation operations. The copy and paste method should make due for...

    Ti NSpire cx - 2 questions, last equation, and touch pad?

    Sorry, title limited on what I could type. I just got this calculator and am having two big issues with it. 1) I cannot figure out how to reuse my most recently typed equation. For example if I type in a insanely long multiple variable equation and evaluate, the only way I can figure out how...

    Is there a way to calculate gas flow rate from output PSI?

    I've noticed that certain propane torches will have a seemingly linear relationship between their PSI and BTU/hr. IE, 18 PSI -> 220,000 BTU/hr. From this a person could calculate how much gas is being burned per sec/minute/hr. So, is there a general relationship/formula that I can use to...

    Calculating Average Emission Wavelength from Spectral Intensity Chart

    I haven't had calculus in over 2 years and so I am not exactly sure how to go about this. I am inclined to believe some form of integration would be needed. I took the chart below from a paper on LED wavelength emission. The authors say that the vertical line represents the average emission...

    Is it possible to partially reflect microwaves as we can do with light?

    I understand the basic functioning of a microwave, but my question was more focused on the actual mechanics of how an object might could reflect a fraction of microwaves that hit it, while letting the rest past through, while absorbing none. My curiosity stems from my recent research into LASING...

    Is it possible to partially reflect microwaves as we can do with light?

    Different types of mirrors and reflective surfaces can be set up to reflect predetermined amounts of light, like 70% of it, or 30%, or 99% of it, while letting the rest through. Can the same be done with microwaves? It seems even very very weak metal cages can completely reflect microwaves. Is...

    Where could I find a high-amp constant current power supply?

    Thanks for that! This one is definitely more affordable than the other ones of similar ability that I had looked at

    Where could I find a high-amp constant current power supply?

    I will look into it. On such a device, with constant current mode, the voltage auto adjusts, correct? I was somewhat thrown off by when you said to set both the voltage and the current.

    Where could I find a high-amp constant current power supply?

    I intend to electroplate very large items as well as other related applications. I just need the current to be a high number, in the range of 600-1000, steady. CC - Constant current. How Constant? I was under the impression most CC power supplies can keep the current decently constant by...

    Where could I find a high-amp constant current power supply?

    I've seen many of these... trying to stay under $1,000. I do not need the system to be variable, which I think is what really hikes the price up, but rather I need a constant and steady high current output. For instance 200 amp welding power supplies are a few hundred bucks... but a 200 amp...

    Where could I find a high-amp constant current power supply?

    The max voltage I would need would be 2, maybe 2.5 volts tops.

    Where could I find a high-amp constant current power supply?

    All of the ones I've seen online can only do about 30 amps tops... then there are welding machines, which I am not sure if those can used for non-welding applications without modification of the machine. I am not looking for something that is variable, just something that can output a high...

    What are some nonreactive electrolyte solutions?

    I have an alcohol that I need to hydrogenate/reduce and I would like to do it electrochemically. The catholyte solutions I am used to using are basic sulfuric acid, but that would not work in this case as it would cause a violent reaction with the alcohol. The alcohol could be reduced with an...

    Where can I have custom made a variable dc switching power supply?

    I contacted a sales rep from the company that berkeman linked and they have pointed me in the right direction and explained what I would need to accomplish my goals. Thank you to everyone for the replies here!

    Where can I have custom made a variable dc switching power supply?

    Even at 2400 maximum watts? (6v * 400a) I looked up some videos of these devices and it does seem that while they do have knobs for both voltage and current, setting the current to one thing will auto-adjust the voltage to maintain the current depending on the resistance of the system.
