A compression member having gross effective cross-sectional areas of 1500 mm² and 1250 mm², respectively. If the compressive stress is 150 MPa, the design compressive strength of the column will be:

What will be the maximum possible uniformly distributed load (inclusive of self-weight) over the entire span of a simply supported beam of span ‘L’ such that the deflection at midspan at service condition is zero? The cross-section is rectangular. The prestressing force ‘P’ is applied with uniform eccentricity ‘e’. Assume no losses.

A coarse-grained soil has a voids ratio 0.75 and specific gravity as 2.75. The critical gradient at which quick sand condition occurs, is

Three turbines each of capacity 10000 kW are installed at a hydel power station. If the peak load and the average load produced during a certain period are 25000 kW and 15000 kW respectively, then load factor and plant factor are respectively equal to

In the Gulp method of stream gauging by dilution technique, 60 litres of chemical with concentration of 250 g/lit is introduced suddenly into the stream at a section. At d/s monitoring section the concentration profile of chemical X that crossed the section was found to be triangle with a base of 10 hr and peak of 0.01 ppm. Estimate the discharge in the stream in cumecs.

Lining of canal is necessary:-
