Q1/ Find the maximum allowable load for a square foundation (3 m x 3 m) placed
vertically in cohesive soil? (Use Terzaghi equation)
Note:
Yt=Yeat=18 kN/m³
Depth of foundation = 1.5 m
Depth of water table below the ground surface = 0.8 m
Factor of safety 3
C=20
Yw = 10 kN/m³
=
No vertical or inclined loads
P.3.3
Oil of sp.gr. 0.9 flows through a vertical pipe (upwards). Two points A and B one
above the other 40 cm apart in a pipe are connected by a U-tube carrying mercury. If
the difference of pressure between A and B is 0.2 kg/cm²,
1- Find the reading of the manometer.
2- If the oil flows through a horizontal pipe, find the reading in manometer for the
same difference in pressure between A and B.
Ans. 1- R= 0.12913 m, 2- R = 0.1575 m,
