As a property manager of an 8 story commercial building with 2 boilers, 2 chillers and 2 giant cooling towers...these videos are very helpful in the beginning of understanding what I'm looking at. Many thanks to everyone involved!
Are you in NYC by chance ?
@@thebutcher1412 Unfortunately, I'm in California lol
@@KP-ol3tc ahh okay, while your on the management side of things I’m in the operating engineers union that runs all your equipment lol so I’m starting to learn all this equipment on the flip side of things
@@thebutcher1412 Well good on ya cuz this kinda stuff is for the real thinkers out there! My building was built in 1979 and our modern taught hvac engineers are still amazed by the work of the original contractors.
This videos are fantastic. You are doing a huge favor to the engineering and worldwide community as a whole.
Thank you!
Thank you for the video explanation. Previously I read about npsh, but didn't understand what npsh was. After seeing this video, I immediately understood. Thank You 3:03 3:03 3:03
These past few videos go great hand on hand with the teaching sfor millwright as we have the same explanation as to why we have to make sure the pump is setup right and make sure to take note of the readings of everything, to lubrication to the way the pump was aligned and assembled and what its use it for
I work with Electric maintanance in sewer pump stations. Its really nice to see and understand how the pumps work.
You are amaaazing really in explanation. Very clearly to the point
Short and very clear. ❤
Ta add a few details to this; The NPSHR will also depend on where the pump is operating relative to its design / best efficiency point. At this point the NPSHR is at its lowest. Going to higher or lower flow this will add eddies as the flow does not match the impeller`s blade angle, i.e the more off design the pump operates, the larger eddies, the lower the local pressure inside the eddies will be, hence generating cavitation bubbles (steam, not air as stated in this video). This can be very dramatic for pumps operating way off-design and result in cavitation damages even though NPSHA > NPSHR,a very common thing to see in the industry..
wao! you explain this topics so easy to understand😁
Thank you so much
Awesome easy to understand.
I love this channel
If your NPSHR is the
Same as NPSHA is that okay? Or how much (in%) would you size the pump over by?
So, from my understanding of cavitation, it's not the boiling of water but the creation of air pockets from sudden absence of an object in water. You get cavitation from a rapidly spining boat propeller without the water boiling.
Great ❤️ ❤️ ❤️ ❤️ ❤️
I have a question. After watching all of the videos on electricity generation on the channel, I am confused about the North America system. In one video it is listed as 3 phase generation and transmission. It is then stepped down in the neighborhood and local lines are tapped between one of the three phase lines and neutral for 120v or across all phase lines for
208v.
In another video, it is listed as a split phase where the secondary of the transformer is 240v with a neutral tap off the center for 120 between one end of the secondary and neutral or 240v between the two ends of the secondary.
These sound contradictory. What does the secondary of the neighborhood transformer look like? Is it three separate secondary coils for 120v each coil or is it a single coil with a center neutral tap for 120v over half the coil and 240 over the full secondary coil?

It’s not an acronym, it’s an initialism, just saying.
