Steam at 1400 kpa and 350°c [state 1] enters a turbine through a pipe that is 8 cm in diameter, at a mass flow rate of 0.1 kg⋅s−1. the exhaust from the turbine is carried through a 15-cm-diameter pipe and is at 50 kpa and 100°c [state 2]. what is the power output of the turbine?
h1 = 3150.7 kj/kg v1 = 0.2004 m3/kg
h2 = 2682.6 kj/kg v2 = 3.4181 m3/kg

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
