Hello there, I am currently using LDVT probes to measure linear displacement (goes without saying, but I said it anyway). The problem with this is that the wire for the probe is very cumbersome and requires extra machining to external parts in order to accommodate the wire without disruption...

Thanks for the replies, guys! I will look into these! Quick question about the microwave motors, though... For ones that are similar to the kind on this page (http://www.repairclinic.com/Microwave-Motor-Parts) there they have the L1 and L2 leads to power it, is there a way to power these motors...

For a special project, a team and I are trying to create our own automatic golf ball tee setter. To make a long story short, I need a motor, but I've never purchased motors before, and my EE skills are pretty weak, so I need some help... Here are some specs that I need to meet: The motor...

I say "silly" because I'm actually baffled that I can't figure this out. I'm just forgetting the basics and am stumped at how to correctly approach this. Let's say I want an AC motor that is connected to a shaft which is, in turn, connected to a metal plate. I know the weight of the shaft and...

anyone? any insight would be greatly appreciated.

I have a question about calculating the pressure drop in a large flow meter across an array of nozzles. Basically its inside of a tunnel... air flows in this tunnel until it reaches a "gate" which is blocked off except for six nozzles of different size, which discharge back into an open...

WRP, thank you for your help and sorry for all of the confusion... let me show you what I've obtained. You can show me anything I may have messed up, but the numbers are starting to agree... Taking 1 to be in the pipe and 2 to be at the orifice exit \frac{v_{1}^{2}}{2} + gz_{1} +...

I'm sorry, perhaps I just wasn't being clear enough. My first post is kind of all over the map... I don't know the pressure at the orifice (exit), that's what I want to know. But I am also not sure of the velocity, which becomes a problem with trying to figure out pressure drop. I have a flow...

so if hL = K(v2/2g) where K = 0.9 v = 10.25 m/s g = 9.81 m/s2 this would yield hL = 4.82 m so each 90 bend in this pipe is equal to almost 5 m of head?? that seems kind of extreme, but I guess I have no argument why that wouldn't be the case... I find it strange that this way...

Hello everyone. I have natural gas (methane) flowing through some piping, and the last little part of pipe is where I'm concerned. The gas goes through a drawn aluminum tube, about 5.08 mm ID (it's a very small tube). The tube has three 90 degree bends where it ejects out of an orifice. It...

Ah, I see... the hose is, in fact, convoluted... Next time I am over in the lab, I will check to see the brand/type so I can give a more accurate description. It's nominal size is 3/4"... I'm not sure what the actual ID/OD measurements are, but the OD definitely looks < 1". Perhaps it's...

well, I think therein lies (one of) the problem(s)... the flow meter is giving us numbers, but we're not sure if they're correct. so we really don't know what the flow rate is.

I've got natural gas flowing to a chamber with a regulator set at 9 inWC. The gas then goes through a mass flow meter with a 1/4" diameter hole, which causes a pressure loss of about 3 inWC (to verify this, I have another pressure gauge after the flow meter which accurately reads 6 inWC... After...

Hello, I am trying to do an analysis of an Xbox (funny, I know), and I'm going to try and redesign the cooling system, with different fans/heat sinks and such... To perform my before/after analysis however, I will need to know some things about the GPU, since those are the main heat...

Yeah, I know the pump will be a very small one... I'm actually more worried about getting a pump that's way too big, (cost issues, etc). so if I can calc pressure loss from (rho*g*h), how do piping losses factor in? Looking at the tank, I'm probably going to need about four 90 degree elbows in...
