Lysimeter and Tensiometer are used to measure respectively, one of the following groups of quantities:

Hyetograph is a graph representing

A prestressed concrete rectangular beam of size $$300\,\,mm \times 900\,\,mm$$ is prestressed with an intial prestressing force of $$700$$ $$kN$$ at an eccentricity of $$350$$ $$mm$$ at midspan. Stress at top due to prestress alone, in $$N/m{m^2}$$ is

A hall is covered by a beam and slab system with beams placed at $$3.0$$ $$m$$ center. The effective span of the beam is $$8.35$$ $$m.$$ The thickness of the slab is $$120$$ $$mm.$$ The size of the beam below the slab is $$230$$ $$mm$$ width and $$380$$ $$mm$$ depth. The beam is reinforced with two numbers of $$32$$ $$mm$$ diameter steel rods of grade $$415\,\,N/m{m^2}.$$ Compute the Maximum total load/$$m$$ run, the beam can carry, including its own weight at service stage. Grade of concrete is $$M$$ $$25.$$
