Areservoir has 200 million m^3 capacity. from the watershed, 1000 ppm sediment load comes to the reservoir. void ratio of the soil is 0.3. annual intow of water to the reservoir is 10 times more than the capacity. use a trap emriciency of 80 %. find the years needed to fill the reservoir completely. density of water and saturated sediment are 1000 and 2700 kg/m^3 respectively.

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.

Give heat transfer applications for the following, (i) gas turbines (propulsion) ) gas turbines (power generation). (iii) steam turbines. (iv) combined heat and power (chp). (v) automotive engines
