    useless conundrum

    Hi guys, This has been rattling around in my brain for some time. It's strictly anecdotal but bothering me just the same. Why does my wife's cigarette smoke get pulled out of the car window when I'm driving? Bernoulli's law states that a fluid at a higher velocity will have a lower pressure...

    motor speed control

    Hi guys, My apologies if this is a simple question that has already been answered but I wasn't able to find anything helpful in the archives. I'm designing a glorified dryer. The point of this machine is to tumble clothes at a specific speed over a specific time to condition them for other...

    power reading in novelty generator system

    I have an application where my customer wants to have a "Green" musical event. The idea is that there will be a number of cyclists generating power with some kind of meter reading the power generated and then comparing it to the amount of additional power taken from the grid. I want to know if...

    24VDC boost to 12VDC truck

    We have built some military vehicles that operate on 12V but have 24V capabilities. We've done this by using a battery bank with some of the circuits coming off of one set of batteries wired in parallel (12V) and then the other circuits coming off both of the sets of batteries wired in series...

    unloader valve

    I am designing what can best be described as a carwash system. There is a high pressure pressure pump (positive displacement, piston) and a variety of things feeding off the pump (spray bars, spray wands) and there is no way of knowing what the volumetric requirement would be depending on what...

    trouble with sketches in 2005

    SolidWorks 2005, SP 02 I'm creating base sketches in assemblies that I then use to generate a full set of parts from, but for some reason my computer gets really bogged down once my sketch consists of about 10 lines or more. It slows when I'm trying to zoom in or out, rotate or pan and then...

    water combiner

    I'm looking for a combiner to proportionally mix water with two other aqueous solutions. looking at flowrates of about 15 gpm and pressures of about 150 psi with a mix ratio of 16% of A, 16% of B and 68% water. The flow rate of the water will not be consistent in the application so a solution...

    inventor to SW problems

    I'm trying to open inventor files with SW 2005 but solidworks says that there is no solid data in the file. I can open it using the inventor view but I can't get any dimensions from the part. Without re-exporting the file, does anyone know how to look at the inventor files. Thanks Charlie
