A. Perform a mass balance for each set of operating conditions with using mass flow rate data to determine the flow rate of rotameter (6 pt in total). b. Compare the calculated mass flow rate value with the measured mass flow rate of rotameter obtained in the experiment. Plot two graphs one for constant cold outlet cases and one for constant hot outlet cases showing the relative error (%) vs Inlet Mass Flow Rate (kg/s). (6 pt, 3 pt each plot)

When subject to a steady load (within elastic range) over a long period of time, what is the major difference in material behavoir between steel and plastic?

Tom is having a problem with his washing machine. he notices that the machine vibrates violently at a frequency of 1500 rpm due to an unknown rotating unbalance. the machine is mounted on 4 springs each having a stiffness of 10 kn/m. tom wishes to add an undamped vibration absorber attached by a spring under the machine the machine working frequency ranges between 800 rpm to 2000 rpm and its total mass while loaded is assumed to be 80 kg a) what should be the mass of the absorber added to the machine so that the natural frequency falls outside the working range? b) after a first trial of an absorber using a mass of 35 kg, the amplitude of the oscillation was found to be 10 cm. what is the value of the rotating unbalance? c) using me-3.5 kg.m, find the optimal absorber (by minimizing its mass). what would be the amplitude of the oscillation of the absorber?
