Steam enters an adiabatic turbine at 10 mpa and 500 °c and leaves at 30 kpa with a quality of 90 percent. neglecting the changes in kinetic and potential energies, determine the mass flow rate required for a power output of 5 mw.

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
