The subsoil at the site consists of a 10 m thick
homogeneous layer of dense sand having the following properties:

Dry unit weight = 16 kN/m3,
Gs = 2.68,
angle of friction = 35 degrees

The natural ground water table lies at 2 m below the ground surface.

WITH COMPLETE SOLUTION
PROBLEM 1:
An infinite slope contains soil whose saturated unit weight is 18.639 kN/m^3 . There is a seepage through the soil and the groundwater table coincides with the ground surface. The cohesion and angle of friction are 30 kPa and 25°, respectively. Which of the following gives the factor of safety against sliding on the rock surface?
PROBLEM 2:
Calculate the excess pressure (above atmospheric) inside a soap bubble of radius 5 mm. The surface tension of the soap solution is known to be 0.042 N/m, in Pascals.
PROBLEM 3:
A tank contains oil (SG=0.80), gasoline (SG=0.90) and water(SG=1.05). What is the pressure at a depth of 1.20 m (in kg/m 2 ), if the depths of the liquids are 0.50 m, 0.60 m and 0.80 m respectively?

An existing unlined channel is having the following dimensions:

Bottom width = 1.52 m; Side slopes = 1:1; Flow depth = 0.90meter; and

Bed-slope = 1/1667.

It is proposed to line this channel for the same discharging capacity. Find out the dimensions of the lined channel and work out the economics of the concrete lining, if following data are given:

Length of irrigation season = 150 days;

Saving in seepage loss by lining the canal = 1.5 per cent per km

Cost of water = Rs.150 /ha/m; Cost of concrete lining = Rs.16 /sq. m

Cost of reshaping and trimming canal = Rs. 4.00 per sq. m.

Life of lining = 40 years; Interest rate = 7 percent.

Annual maintenance and operational cost (rupees per km per year)

for unlined canals earth = Rs.1000; for concrete lined canals = Rs. 200

Other additional benefits = Rs. 350.00

Assume any other necessary data, if not given.
