The percentage error in the computed discharge over a triangular notch corresponding to an error of 1% in the measurement of the head over the notch, would be

The treatment that should be given to the water from a deep tube well is :

A reinforced concrete column contains longitudinal steel equal to 1 percent of net cross-sectional area of the column. Assume modular ratio as 10. The loads carried (using the elastic theory) by the longitudinal steel and the net area of concrete, are P_s and P_c respectively. The ratio P_s/P_c expressed as percent is

In a reinforced concrete beam-column, the increase in the flexural strength along with the increase in the axial strength occurs

A lysimeter is used to measure :

Presence of ifluoride in water greater than permissible level of 1.5 mg/l causes

Three reservoirs A, B and C are interconnected by pipes as shown in the below figure Water surface elevations in the reservoirs and the Piezometric Head at the junction J are indicated in the below figure.

Discharges Q₁, Q₂ and Q₃ are related as

A wastewater sample contains 10^-5.6 mmol/l of OH ions at 25° C. The pH of this sample is

The force in the member DE of the truss shown in the below figure is,

The plastic modulus of a section is 4.8 x 10^-4 m³. The shape factor is 1.2. The plastic moment capacity of the section is 120 kN.m. The yield stress of the material is

Standard 5-day BOD of a waste water sample is nearly x% of the ultimate BOD, where x is

When a retaining wall moves away from the backfill, the pressure exerted on the wall is termed as

The forces in members 'a, b, c' in the truss shown are, respectively

A simply supported beam with an overhang is traversed by a unit concentrated moment from the left to the right as shown below

The influence line for reaction at B is given by

Generally the maximum deflection/span ratio of a steel member should not exceed

In an area of 200 hectare, water table drops by 4 m. If the porosity is 0.35 and the specific retention is 0.15, change in volume of storage in the aquifer is

A continuous beam is loaded as shown in the figure below. Assuming a plastic moment capacity equal to M_P, the minimum load at which the beam would collapse is

The magnitude of the bending moment at the fixed support of the beam is equal to :

The disinfection efficiency of chlorine in water treatment

If the shear force at a section of beam under bending is equal to zero then the bending moment at the section is
