.流量 风机的流量是用出气流量换算成其进气状态的结果来表示的,通常以m3/h、m3/min表示。但在进出口压比为1.03以下(比如通风机范畴的风机)时,通常将出气风量看作为进气流量相同。 流量亦称为气体...
2.压力 为进行正常通风 需要有克服管道阻力的压力 风机则必须产生出这种压力。风机的压力分为静压、动压、全压三种形式。其中克...
3.功率 风机的原动力(通常是电机或柴油机等)传递给风机轴上的功率为风机的轴功率N...
I haven’t posted in forever, but I was inspired this evening to just document what I have found to be the best approach for perfect hard-boiled eggs. What do I mean by perfect hardboiled eggs? Two things: (1) the yolk is cooked to the hardness I like, and (2) the shell peels off easily without that annoying sticking of egg white to the shell. (For the food nerds out there, my understanding, via an explanation I read in Cooks Illustrated, is that by dropping the eggs into boiling water you cause the membrane surrounding the egg white to bond to the shell allowing for easy peeling. Whereas if you bring cold eggs and water to a boil together, the membrane bonds to the egg white and the shell causing that annoying pocking of the egg white– or something like that.)

Total time from start to finish is about 20 minutes — with only about 2 minutes of actual work time, the rest waiting for water to boil and eggs to cook. We all should have a carton of HBs in the fridge all the time. No excuses not to.
Everyone in the engineering world knows McMaster-Carr, but few people in the DIY world do. McMaster is a privately held company based in Illinois that may be the world’s largest engineering superstore. They have hundreds of thousands of items and in twenty plus years of using them I don’t think I’ve ever experienced a stock out. Remarkable.

They have everything. What do I mean by “everything”? Well, you can buy stainless steel spring wire, storage bins, a work bench, a belt sander, fasteners, and (literally) a kitchen sink.

You wouldn’t want to use McMaster for something you can get at Home Depot, even though they have almost everything Home Depot does, but they fit the bill when you need something a little bit out of the ordinary or you want to use an industrial/commercial product in your personal project.

Here are some nice items I’ve used them for in my projects:

    Copper sheet.
    John Boos “butcherblock” countertops (under “Maple tops”) at $16/sq-ft
    Richlite lab bench material (the predecessor to the oh-so-trendy Paperstone…called “phenolic tops” at McMaster) at $26/sq-ft
    Heavy-duty urethane casters to support a huge rolling shelving unit.
    Acme threaded rod for shelf supports.
    Any manner of weird drill bit or fastener.
    “Speedrail” tubing fittings for railings, etc.

They take credit cards. They ship the same day by UPS.

My workbenches shown here (on the left) have McMaster tops (both butcher block and Richlite).
McMaster-Carr Supply Company is a private supplier of hardware, tools, raw materials, and maintenance equipment and supplies. McMaster maintains a wide variety of mechanical, electrical, plumbing, and utility hardware not usually located from a single source.
