Question Solved1 Answer   right solution please In the figure below, the pipe carrying feed-water to a boiler in a thermal power plant "the pipe can be modeled as spring-mass system" has been found to vibrate violently at a pump speed of \( 427 \mathrm{rpm} \). If the operating speed range of the pump is between \( 360 \mathrm{rpm} \) to \( 900 \mathrm{rpm} \). In order to reduce the vibration, an absorber consisting of a spring of stiffness \( k_{2} \) and a trial mass of \( 10 \mathrm{~kg} \) is attached to the pipe and tuned to the \( 640.5 \mathrm{rpm} \) speed, i.e. tuning ratio of \( 1.5 \). This arrangement is found to give natural frequencies of the system at \( 342 \mathrm{rpm} \) and \( 800 \mathrm{rpm} \). Design the absorber to be attached to the pipe, i.e. calculating its mass \( \boldsymbol{m}_{2} \) and stiffness \( \boldsymbol{k}_{2} \) to satisfy the above-mentioned requirement ( to keep the natural frequencies of the system outside the operating range).

5. Linear power supply Use lecture 2.1 to design an unregulated power supply (that is no regulator) that will deliver a minimum of 12 V with a maximum of 1 V ripple when the current supplied to a load is 50 mA. Use a half wave regulator. Determine a value for the capacitor. What is the output of the transformer's secondary in rms.
