An area consists almost entirely of sandy loam with a saturated hydraulic conductivity of 11 mm/h, average suction head of 110m, porosity of 0.45, field capacity of 0.190, wilting point of 0.085, and depression storage of 4 mm. The design rainfail is given by: Interval (min)Average intensity (mm/h) 0-10 20 10-20 40 20-30 60 30-40 110 40-50 60 50-60 20 Assume the initial moisture conditions are midway between the field capacity and wilting point..

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
