Two tanks (tank a and tank b) are separated by a partition. initially tank a contains 2 kg of steam at 1 mpa and 300°c while tank b contains 2.8 kg of saturated liquid–vapor mixture at 150°c with a vapor mass fraction of 50 percent. the partition is now removed and the two sides are allowed to mix until mechanical and thermal equilibrium are established. the pressure at the final state is 300 kpa. determine:
(a) the temperature and quality of the steam (if mixture) at the final state.
(b) the amount of heat lost from the tanks.

An engine, weighing 3000 n, is supported on a pedestal mount. it has been observed that the engine induces vibration into the surrounding area through its pedestal at the maximum operating speed. determine the stiffness of the dynamic vibration absorber spring in (n/m) that will reduce the vibration when mounted on the pedestal. the magnitude of the exciting force is 250 n, and the amplitude of motion of the auxiliary mass is to be limited to 2 mm note: in this question type-in right numbers, no decimals, no fractions, no unit. approximate to right number if needed
