Agas turbine is supplied with an ideal gas mixture having the following gravimetric analysis: 19% argon, 10% helium, and 71% neon at 500 k, and 0.3 mpa. products exit the turbine at 350 k, and 0.11 mpa. assuming an isentropic turbine, what is the work developed by the turbine per kilogram of gas mixture?

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
