Water from an open reservoir a at 8m elevation is drawn by a motor driven pump to an open reservoir b at 70 m elevation. the inside diameter of the suction pipe is 200 mm and 150 mm for the discharge pipe. the suction line has a loss of head 3 times that of the velocity head in the in the 200 mm pipe. the discharge line has a loss of head 20 times that of the head in the discharge pipeline. the pump centreline is at 4 m. overall efficiency of the system is 78% for a discharge rate of 10 li/s, find the power input to the motor and the pressure gages reading installed just at the outlet and inlet of the pump in kpag

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.
