A vibrating body is supported by six isolators each having stiffness 32000N/m and six dashpots having damping factor as 400 N-s/m. The vibrating body is to be isolated by a rotating device having an amplitude of 0.06 mm at 600 rpm. Take m = 30 kg. Determine (i) Amplitude of vibration of the body (ii) Dynamic load on each isolator due to vibration.
five kilograms of water are contained in a closed rigid tank at an initial pressure of 20 bar and a quality of 50. heat
During an experiment conducted in a room at 25°C, a laboratory assistant measures that a refrigerator that draws 2 kW of power has removed 30,000 kJ of heat from the refrigerated space, which is maintained at -30°C. The running time of the refrige..
A curde oil storage tank the tank initially contains 1000m^3 ofcrude oil. Oil is pumped into the tank through a pipe at a rate of 2m^3/min and out of the tank at a velocity of 1.5m/s through another pipe having a diameter of 0.15m. the crude oil has ..

thirty units were placed on test in order to estimate the reliability of the shift driver over a 200 operating hour
initially 0.05 kg of air is contained in a piston-cylinder device at 200 degc and 1.6 mpa. the air then expands at
water vapor is cooled in a closed rigid tank from 520 c and 100 bar to a final temperature of 270 c. determine the
During the process, a pressure-relief valve allows nitrogen to escape, maintaining constant pressure in the tank. Neglecting kinetic and potential energy effects, and using the ideal gas model with constant specific heats evaluated at 350 K, deter..
air enters the compressor of an ideal closed air-standard brayton cycle at 100kpa with a volumetric flow rate of 5m3s.
It is found experimentally that the terminal velocity ut of a spherical particle in a fluid depends upon the diameter d of particle, the dynamic viscosity it of fluid and the buoyancy weight W of the particle [given by the difference in density betwe..
