A fluid flows through a horizontal pipe of radius 0.02m. the pipe is turned up to a height of 10m and a horizontal pipe connected to the other horizontal pipe with the radius 0.04m. determine the fluid flow so that pressure on the both horizontal pipes are equal. A beam spring system has a mechanical energy by oscillating 1 Joule, with an amplitude of 10cm, and a maximum speed of 1.20m/s. Find (a) spring constant (b) the mass from the beam (c) the frequency of oscillation.
