A refrigeration cycle operating between two reservoirs receives energy QC from a cold reservoir at TC 5 275 K and rejects energy QH to a hot reservoir at TH 5 315 K. For each of the following cases, determine whether the cycle operates reversibly, operates irreversibly, or is impossible: (a) QC 5 1000 kJ, Wcycle 5 80 kJ. (b) QC 5 1200 kJ, QH 5 2000 kJ. (c) QH 5 1575 kJ, Wcycle 5 200 kJ. (d) 5 6.

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
