Do you offer some video training?

Nice video

Please tell me more about the impromptu head calc , how did u get the head of the system? Same about the TDV . Looking forward to hear from you the soonest .

If a pump is deemed to be slightly oversized. What operators do is get a butterfly valve installed and throttle it. There are various reasons why it can oversized. Such as the engineer being overly cautious, or considering prospect of expansion ie pump will be more loaded in a future scenario.

شكرا جزيلا لمجهودكم الممتاز

Thank you. At 7:29 if i have one hose and gauge, would I take the psi reading from the outlet , then inlet and add them together?

Thanks! Good explication HVC technician student

I went to a local college and took Electromechanical Engineering Technology (Building Automation) and you have done a great job of teaching some of the most important concepts from my many courses and how they play together in under 15 minutes WOW! You have earned your subscription and I am looking forward to checking out more of your videos!!!

From the curve it shows that head is against the flow and if we need to increase the flow we need to add more head ?

So in entry level Hvac words….what is enthalpy?

I must say, this is one of the best explanation. Thank you

love it

Are the AHU and VAVs working together in conjunction based on the BAS sequencing?

Seriously speaking..YOU are doing a great job

Nice information

Is there an email where I can reach you to ask some more in depth pump questions?

how does suction head work into this? with a higher pressure at suction, you get better discharge flow..
