Thanks to you Sir ,for explanations about hvac design pump head selection along with project drawings. Scheme. Elevation plan. Head loss & friction factor calculation..
Very very helpful for future reference.... But one doubt... Please clarify..... In Condenser Water Pump system, do we need to calculate the friction losses for the pipes and fittings of the CONDENSER WATER RETURN (i.e., from the cooling tower to the chiller) as well.??? Or only the friction loss needs to be calculated from the chiller to the pump's suction and then from the pump's discharge to the cooling tower only...?? Please clear this doubt of mine
Sir your video is very helfful for us. Sir i have one question about the length of pipe. Because chilled water system have supply and return pipe,so we take both pipe for length. Example CWS pipe length 30 meter and return 32 meter , so total length is 62 meter
Really appreciated your efforts ... but i have one confusion ........ why you have not taken vertical height head of 85 feet from basement (pump) to roof top (cooling tower) because it is open loop circuit & hence we have to consider vertical height head of 85 feet ( 85 feet is the height distance from basement to roof top).. can you plz explain???
I have explained in video. However, This is loop piping but open-loop. Here we have to take open height of water, from cooling tower bottom to top only.
Hi Sir, Do you have any video on chilled water expansion tank sizing and installation video. Can you please recommend one. Or can you please explain from any of your old projects. Thank you.
Very helpful, but only one confusion.. my question is that for straight vertical pipes.. there will be head loss due to height difference ...then where we will put this head loss in vertical pipes due to height difference in excel sheet..... example pump is at lower level & cooling tower is at higher level then there will be vertical straight pipe that connects both & in this case there is some head loss due to height difference ..... where we will put this head loss ..... just like condenser pumps are in basement & cooling tower is at roof top .. then in shaft there will be vertical pipe that connects condenser pump & cooling tower .... in this case there is head loss in vertical pipes in shaft due to height difference ... so where we will take this head loss in our excel sheet???
@@TanweerAhmed ... In video, Static Head is explained that it is the height of Cooling Tower ... but for vertical pipes & the pipes that are in shaft or riser that has height differences from basement to roof top .. for this case, Static head or head loss or friction loss due to height differences is not mentioned... please kindly explain... thanks
Assalam o Allium Sir...can you plz explain why do v don't insulate condensate water line coming back from cooling tower to the condenser of the chiller
W.Salam, Because water temperature of that pipeline is high or near to atmosphere temperature therefore water does not condensate over the pipeline like drinking cold water glass🍷 💦
@@TanweerAhmed okay Sir but the returning water is coming out of cooling tower where temperature drop has taken place, if we do not insulate the line which is carrying the cooled water from cooling tower (rooftop) to chiller (normally placed in basement) then during summer days, will not their be heat excahnge which will eventually result in cooling lose inside the CWS line?
We have installed cooling tower and chiller on roof top so we have to calculate just distance from pumps to cooling tower or we have to add riser length also
@@VijayKumar-he9rx I have explained in the video that the whole looped pipe network of remote location equipment with riser pipe but branches pipes and equipment will not be considered in the calculation if you want to pump head calculation.

Jazaka"Allah, Complete open loop to be calculate including pipe, fittings, valves, equipment, et....
@@TanweerAhmed that means we need to calculate CONDENSER WATER RETURN also including pipe fittings and valves till CHILLER... CORRECT??

Dear Sir, please make more videos about elevators, we are waiting since long time
Ok dear, I have start working
Sir your video is very helfful for us.
Sir i have one question about the length of pipe. Because chilled water system have supply and return pipe,so we take both pipe for length. Example CWS pipe length 30 meter and return 32 meter , so total length is 62 meter
Yes both length will be consider

sir in both laminar and turbulent flow we will use same hazzen willian and darcy equation
Yes can use but condition to condition formula application change. I have explained in this series of videos regarding formulae application

Sir which standard table do you use for fittings and valve data
Thanks
Tables are attached in excel sheet and link is given in this video's description
very helpful. i have a query, instead of using the equations can we use pipe sizer software to get the friction loss ?
If use the software then compare the both values, if found same then no problem.

Sir how can we calculate pipe length from pump to cooling tower.
Through inchi tap practically. Or through drawing scale
We have installed cooling tower and chiller on roof top so we have to calculate just distance from pumps to cooling tower or we have to add riser length also
It is simple. What is problem there?
@@TanweerAhmed I can't understand it
Because we have pumps near to chiller so we have to just measure that or whole piping including riser
@@VijayKumar-he9rx I have explained in the video that the whole looped pipe network of remote location equipment with riser pipe but branches pipes and equipment will not be considered in the calculation if you want to pump head calculation.
