Water flows through a pipe at a rate of 20 cfm. the diameter of the pipe is constant at 2 inches. the pressure drop across the 90 °bend in the pipe is 1 kpa. determine the head loss of the bend in meter. assume the density of water to be 1000 kg/m^3 and do not consider major head loss.

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.
