Hi, thanks for the tutorial. Here are my questions 1. How do you know the number of floor where the min required pressure won't be available. 2. Is the 1.5bar min pressure the required pressure of any fixture in the floor? Lets say WC flush tank 3. How did you arrive at 1.6bar for the floor with gravity supply
First calculate required pressure for each floor. Check the required pressure for fixtures and appliances from catalogue. Consider maximum pressure fixture .if you have water tank on roof then calculate pressure by gravity at each floor in the riser. if riser pressure is less than required then you need to supply this floor by booster. Please watch this video again, I think you will understand. then for any doubt you can write me, here or can send email also. I will clarify you. For each feet riser you need 0.433 psi pressure.
How did u know 0.33 bar pressure for each floor without booster pump? Any formula ot refrence, somewhere u me tioned 0.433psi per feet and here 0.33 bar per floor. Plz clarify
we selected terrace booster pump at 1.5 bar, it is the minimum pressure required for top floor, as we go down the pressure in the network will be = booster pump pressure +pressure by gravity duty level difference. at 14th floor 0.33 bar is pressure due to level difference & 1.5 bar is by booster pump. Floor height =11 ft pr to lift water 01ft = 0.433 psi Pressure for 11ft = 0.433x11= 4.763 psi = 0.328 bar = 0.33 bar
Thank you sir . Sir kindly agr ap k pass table ho ya excel sheet ho k Kitne gpm k leye Kitna pipe size caheye . To sir ye sheet description me dalde . Shukria
You can contact us on email given in channel description, try to learn, I have uploaded complete tutorial for domestic water supply system, after that you can ask if some thing is not clear to you, or you need any specific table or chart.
1-calculate pressure required for each floor. 2- check if pressure available by gravity is less than required, then feed this floor by booster, 3- Booster pump pressure = max. difference between required pressure & available pressure by gravity at any floor. It is generally pressure required at top floor, as at this level pressure due to height difference between water tank and floor is negligible.
No, peak factor is the ratio of peak demand to mean demand. Observe the peak demand in a day and calculate total demand for one day, this ratio will give you peak factor. If people living in a building are working, then in morning and evening more people use water,peak factor will be higher, if non working then all people will not use water simultaneously, peak factor less.
@@ncengineeringtechnology3376 hi bro, if we have riser height of 30feet let say , so we will simply find riser pressure by multiplying (35feetx0.434 psi) means 15 psi total pressure which is equivalent to almost 1 bar. Like this or anythng else plz let me knw.
Peak factor is different for different locality, you can ask your municipality department for it, as general practice for medium city we consider it 1.5 for small projec you can calculate your daily water demand by per capita method, you watch our video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-NWRCSV1gYgc.htmlsi=yRoQwS4bOSxakl4c
