- In its natural condition, a soil sample has a mass of 1.980 kg and a volume of 0.001 m3. After being completely dried in an oven, the mass of the sample is 1.800 kg. Specific gravity G is 2.7. Unit weight of water is 10 kN/m3. The degree of saturation of the soil is:
- The ratio Nf/Nd is known as shape factor, where Nf is the number of flow lines and Nd is the number of equipotential drops. Flow net is always drawn with a constant b/a ratio, where b and a are distances between two consecutive flow lines and equipotential lines, respectively. Assuming that b/a ratio remains the same, the shape factor of aflow net will change if the
- Following statements are made on compacted soils, wherein DS stands for the soils compacted on dry side of optimum moisture content and WS stands for the soils compacted on wet side of optimum moisture content. Identify the incorrect statement.
- Four columns of a building are to be located within a plot size of 10 m * 10 m. The expected load on each column is 4000 kN. Allowable bearing capacity of the soil deposit is 100 kN/m2. The type of foundation best suited is
- For subcritical flow in an open channel, the control section for gradually varied flow profiles is
-
Group-I contains dimensionless parameters and Group- II contains the ratios.Group-I Group -IIP. Mach Number 1. Ratio of inertial force and gravitational forceQ. Reynolds Number 2. Ratio of fluid velocity and velocity of soundR. Weber Number 3. Ratio of inertial force and viscous forceS. Froude Number 4. Ratio of inertial force and surface tension forceThe correct match of dimensionless parameters in Group- I with ratios in Group-II is:

Some of the water quality parameters are measured by titrating a water sample with a titrant. Group-I gives a list of parameters and Group-IIgives the list of titrants.Group-I Group-IIP.Alkalinity 1. N/35.5 AgNO3
Q. Hardness 2. N/40 Na2S2O3R. Chloride 3. N/50 H2SO4S. Dissolved oxygen 4. N/50 EDTAThe correct match of water quality parameters in Group-I with titrants in Group-II is: - A water treatment plant is designed to treat 1 m3/s of raw water. It has 14 sand filters. Surface area of each filter is 50 m2. What is the loading rate (in m3/day . m2) with two filters out of service for routine back washing? __________
