    Optics: Reversing a Nuetral Density Filter

    Are there sample problems or instructional texts somewhere that go over light/energy transmission through layered optical mediums?

    Is engineering really like this?

    This is a pretty humorous picture...and yes, I'd say accurate too. But don't let that discourage you. Often I find myself nose deep in equations that look like this when you sprawl them all out to look complicated, and that's something I would have found horrifying in the early years of my...

    Flow rate calculation using pressure difference and time

    http://www.air-dispersion.com/feature2.html At this link, you should use the Rasouli-Williams model. The equation they give is set up for iterating to give you a time-dependent response. (Pay careful attentions to units here...if you run into trouble you can PM me, and I'll forward you a...

    Optics: Reversing a Nuetral Density Filter

    I'm conducting a heat transfer analysis on an instrument, but must first overcome my apparent lack of knowledge of optics. Light is incident on a neutral density filter. The ND filter consists of 0.050" thick quartz with a a negligibly thin metal coating with emissivity of 0.065 on the...
