Water vapor at 6 mpa, 600°c enters a turbine operating at steady state and expands adiabatically to 10 kpa. the mass flow rate is 2 kg/s and the isentropic turbine efficiency is 94.7%. kinetic and potential energy effects are negligible. let t0 = 298 k, p0 = 1 atm. determine a. the power developed by the turbine, in kw. b. the rate at which exergy is destroyed within the turbine, in kw. c. the exergetic turbine efficiency

Compute the pressure drop of 30°c air flowing with a mean velocity of 8 m/s in a circular sheet-metal duct 300 mm in diameter and 15 m long. use a friction factor, f 0.02, and pair = 1.1644 kg/m a. 37.26 pa b. 25.27 pa n c. 29.34 pa d. 30.52 pa

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
