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!

This videos are fantastic. You are doing a huge favor to the engineering and worldwide community as a whole. Thank you!

@julioguzman5197 Год назад

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

@HavitYoutube 8 месяцев назад

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

You are amaaazing really in explanation. Very clearly to the point

@thomasstromoy3037 Год назад

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..

I work with Electric maintanance in sewer pump stations. Its really nice to see and understand how the pumps work.

wao! you explain this topics so easy to understand😁

@muadiib 7 месяцев назад

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.

@gabrielconstante7054 Год назад

If your NPSHR is the Same as NPSHA is that okay? Or how much (in%) would you size the pump over by?

@davidroddini1512 Год назад

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?
