How did you come up with the 2" pipe Total head at point D to equal 232. Shouldn't it be 1200ft - 67.2 = 1132ft (at 11:15 in the video)? Thank you for the video. Oops it was corrected at 13:26.
P = gamma of water x head (height of water) = 62.4 lb/ft3 x h(ft) = P in lb/ft2 (gamma fresh water = 62.4 lb/ft3 at normal temps) converting to psi = 62.4 lb/ft3 x h(ft) x 1 ft2/144in2 ((12in)^2 = 144 in2) 62.4/144 = 0.433 P in psi = 0.433 x h in ft or h in ft = 2.31 x P in psi
for the above-shown model example, for 55GPM demand/flowrate, may be provided 2" size dia pipeline upto peak point (C) and the pipe size 1.5" to the remaining pipe length to avoid negative pressures at the peak point for 55GPM demand/flowrate. and provide an air valve at peak point (C) in just downstream side of the point (C) to avoid negative pressures at maximum possible gravity flow situations if any.
Great tutorial, thanks for sharing this. Surprisingly we don't have enough engineers in the industry who can do these simple calculations.
Excellent!

Please share the tutorial in metric units
😂😂
Thanks sir ! can you add something on topographic survey of gravity pipe line
Thank you sir
Thanks Sir.
sir thank you
sir can you explain how you get the value of 0.433 psi/ft
P = gamma of water x head (height of water)
= 62.4 lb/ft3 x h(ft) = P in lb/ft2
(gamma fresh water = 62.4 lb/ft3 at normal temps)
converting to psi
= 62.4 lb/ft3 x h(ft) x 1 ft2/144in2
((12in)^2 = 144 in2)
62.4/144 = 0.433
P in psi = 0.433 x h in ft
or h in ft = 2.31 x P in psi
@@thomassoerens246 Thank you sir
Can you please sir give the height in meter not in ft....gamma fresh water also in kg/m3
@@thomassoerens246 Sir i need your help. Can you please share me your e-mail id or whatsApp number
dear sir how i can get the hard copy of these caculation?
Could you please tell me how to fix the issue that occurred in 1.5 inch pipe due to suction?i’ve the similar problem so now i need to fix it
any reply you have recieve please
I have same prblm
