Sir finds a lot
|
I was doing some thermo homework online and I've been missing these problems because I'm not converting properly because I don't know if i need to take it more steps than one conversion at the end of the question. For example I had a question about a fan blowing air constantly down a duct. well when I down in the end of the simple formula and had mair*Vout^2 = (7.40 lbm/s)(16 ft/s)^2 * ((1 Btu/lbm)/(25,037 ft2/s2)) except there was no way for me to know that last part, which of course I didn't (the answer needed to be in watts so they got rid of everything but the Btu's to convert easily into wattage). I was wondering if anyone knew of any sites that had a lot of conversions as opposed to just a calculator that can switch from just one unit to just one other unit. I am only asking because I can see this being a problem the whole semester if I don't get access to a lot of these. |

You'd be surprised, google's calculator is quite impressive at this sort of thing. Could you be more specific about 'a lot of conversions'? I have a series of books here with every conversion you should need, but I don't know where to find one online

A Higher Evolution

Sorry, I was taught the Bastard Metric System. When it comes to enthalpy Farenheit means nothing to me. However, I still work in inches when laying out out print because printers are still Imperial-based (even the Japanese ones). Metric just doesn't work. I wonder what the metric equivalent of Pi is? |
