How would you find the total head at point A if it was somewhere between the equipotential lines instead? Would you use interpolation or another method?

[@MasterCivilEngineering]

Thanks for watching dear

[@MasterCivilEngineering]

You have to find the elevation and distance of the point from the given flow net. As flow net is drawn to scale, find the plotted distance from the diagram and convert it using scale to actual distance.

You seems cool bro,

Sir how to find effective stress if water level is on both side u/s and d/s

[@MasterCivilEngineering]

Thanks for watching!

[@MasterCivilEngineering]

First find the pore water pressure at the point. Then see if the point is close to upstream or downstream and find total stress at the point. Subtract pore water from total stress to get the effective stress

[@MasterCivilEngineering]

I will be making a video on it in the coming days So stay tuned!

[@shubhamkumar-go7rr]

@@MasterCivilEngineering how to decide sir , the pt is closed to either u/s or d/s.

[@shubhamkumar-go7rr]

@@MasterCivilEngineering thank you sir

[@vishal0056]

Sir why did you add 8.5 yw in total stress calculation actually soil is already saturated.
Is this not correct ( ysat*8.5)+(6*yw)

[@MasterCivilEngineering]

Thanks for watching dear

[@MasterCivilEngineering]

I have wrong calculated total stress and actual value is 20x8.5 + 9.81x6 = 228.86 kPa

[@MasterCivilEngineering]

Effective stress = 228.86 - 130.473 = 98.4 kPa

[@msrn7167]

Yes thank you for confirming

[@MasterCivilEngineering]

Thanks for Watching Master Civil Engineering

[@TheAncientColossus]

PORE PRESSURE IS 130KPA. BUT THE VIDEO CREATOR COMMENTS 142KPA. VERY CONFUSING.

[@MasterCivilEngineering]

Thanks for Watching Master Civil Engineering

[@MasterCivilEngineering]

Yes the pore pressure is 130.473 kPa, Thanks for correcting me it was a typing error.

[@niaziworld2464]

good sir

[@MasterCivilEngineering]

Thanks dear

[@nabilahmed7856]

Sir are u an engineer

[@MasterCivilEngineering]

Yes dear

[@MasterCivilEngineering]

U need any help

[@nabilahmed7856]

Civil Engineering Q&A no sir just I wanted to know

[@MasterCivilEngineering]

Ok Thanks for visiting the channel

[@nabilahmed7856]

Civil Engineering Q&A no problem sir

[@keyvanfarshad2761]

I guess total stress in A is wrong, 20*8.5 + 6*9.81.

[@MasterCivilEngineering]

Thanks for watching Master Civil Engineering

[@MasterCivilEngineering]

Yes the value of total stress is 20x8.5 + 9.81×6 = 228.8 KPa

[@mohamednifal6]

I think d part is wrong

[@mohamednifal6]

20×8.5+9.81×6=228.86

[@MasterCivilEngineering]

Thanks for watching dear

[@MasterCivilEngineering]

Yes I have wrongly calculated the total stress value. It's actual value is 228.86 kPa

[@MasterCivilEngineering]

And Effective stress = 228.86 - 142.245 = 86.62 kPa

[@TheAncientColossus]

WHY CHANGE PORE PRESSURE TO 142? NO EXPLANATION.
