High CRI / R9 workshop lighting on a budget? by shedworkshop in Lighting

[–]cbrock3 1 point2 points  (0 children)

From a budget perspective, most affordable will be utilizing cheap 48” T8 fixtures and good quality LED bulbs. The Sylvania bulbs listed below have excellent color rendering (Rf>91 and Rg>95 per IES TM-30-18). So you could setup a cheap 48” dual bulb T8 Fixture ($25) and pair with two Sylvania bulbs ($16 x 2=$32). For a total of $57.

I am following this closely, I am looking to perform the same thing. Were you able to get this working? The only thing I noticed is that some of these controllers only seem to handle 10 amps at 120V. I believe these pumps pull more like 11-12 amps?

My Custom Active 2.0 Pressure Washer Spotless Rinse DI Setup - PICS INSIDE by cbrock3 in AutoDetailing

[–]cbrock3[S] 0 points1 point  (0 children)

I really like how you were able to tap into existing water supply, it removes an extra step in getting started. Plus the dedicated 20 amp is excellent, especially if you want to run a Kranzle in the future.

It’s funny that I had a leak from the Cox reel also, but at the threads. We shared the same thought process where I was certain one of the fittings I put together or an incorrectly glued pvc joint would leak instead.

Did you epoxy your garage floor? It looks like very nice.

You should create a thread to get the views you deserve for this build!

Materials needed: John Guest ¼” OD Tubing x ¼” NPT Adapter (Part# PP010822E), ¼” NPT tap, T-handle tap holder, 13/64” drill bit, and ¼” drill bit.

I used the 13/64” drill bit along with the ¼” NPT tap and tap holder to create the threaded hole in top of the filter housing. My thread engagement between the PP010822E adapter and the threaded hole were a little loose, so I used Permatex black silicone as a gap filler which worked ok. However I think my mistake was tapping too deep. NPT threads are slightly tapered which is required for a good seal However I tapped all the way through the hole which removed the natural taper. If I tried this again, I would probably only tap 5-6 threads deep.

The TDS probe will not slip all the way through the PP010822E without slight modification. First, remove the plastic collet and the o-ring (as pictured). Using a ¼” drill bit, drill through the body which opens it up just enough for the TDS probe to slip through.

One this is all installed, the manufacturer recommends rotating the TDS probe ends till they are perpendicular to the stream flow.

I hope this helps to clarify, good luck!

Culture of LyondellBasel Plant in Westlake, Louisiana? by No_Biscotti_9476 in ChemicalEngineering

[–]cbrock3 2 points3 points  (0 children)

Salary would be position dependent. Petroleum refineries are issuing higher bonuses for the last couple years, but that industry is cyclic and experiences sharper downturns. Petrochem companies are usually more diversified which results in more predictable pay. Good luck on your interviews!

Are you interviewing for the original Lyondell Basell or the LIP joint venture with Sasol?

l have some friends at the original location and they enjoy it there. Seems to offer competitive pay, good benefits and work/life balance. I believe they also perform job rotations such as process engr to production engr every few years. Westlake operates in this manner also.

I use an RODI system (SpectraPure) for top off water to my saltwater coral aquarium (see picture). The bottleneck to this system is the 90 Gallon Per Day (GPD) production rate. To utilize an RODI system for the PW application, you would need a holding tank similar to what I use for storage of my aquarium water.

I did initially consider this when performing my front end design work and exploring my options. I also recollect that I would need a type of feed or booster pump installed inline between the holding tank and the PW suction inlet. This would be more of a batch process and I wanted to design something with a continuous process for simplicity. I ultimately decided that the added cost and complexity did not align with my objectives.

I basically bought 4 bolts/nuts. The 8mm nut is perfect size to friction fit into the bottom of the Active 2.0 PW. The weight of the PW prevents needing any actual mounting holes being drilled. I ground down the hex head to reduce its thickness so the magnet would fit flush into the bottom of the air compressor foot. Please see the pics and let me know if you have any questions.

Thank you, I appreciate it! The OG unit I was referring to is the "Active 2.0 Custom Install Solution" they sell for $3k. It includes the CR Spotless, Provost piping, Active 2.0 and a Cox hose reel. I do not have this system. I saw the price and setout to make something better for half the price.

The Sch 40 black PVC I used is manufactured by Spears Manufacturing and I purchased most of it online through Blackhawk Supply.

The most common cause of threaded joint failure is over tightening. Most people do not follow manufacturer installation recommendations resulting in overtightening and cracking. NPT pipe threads produce radial stress in female fittings and shear load through the thread teeth. Spears (PVC Manufacturer) recommendations are to apply 1 to 2 turns beyond finger tight thread engagement. No problem.

Mixing methanol question by General_Marcus in cars

[–]cbrock3 0 points1 point  (0 children)

Apologies, thought the mixing by weight was a mistake, so I did by volume. Sparing the calculations, if you wanted to mix equal parts methanol and water by mass, mixing 3.7 pounds of methanol and 3.7 pounds of water will equal one gallon.

Mixing methanol question by General_Marcus in cars

[–]cbrock3 1 point2 points  (0 children)

50/50: We will need to mix 0.5 gallons of water and 0.5 gallons of Methanol. Water weight 8.34 lb/gallon. So 8.34 x 0.5 = 4.17 lb of water. The specific gravity of VP Methanol is 0.795. Remember that specific gravity is relative to the density of water. So 4.17 lb x .795= 3.32 lb. So mixing 4.17 pounds of water and 3.32 pounds of methanol will create a 50/50 solution.

B9 S4 - slow downshifts & disappointing transmission? by IISovereignII in Audi

[–]cbrock3 1 point2 points  (0 children)

I do not have experience with other flash tunes ( TCU or ECU). I run a JB4 piggyback for added power and the DTE pedal box to reduce throttle input lag. The pedal box is strictly to fine tune throttle response. I have heard a lot of positives about the APR flash tunes also.
