Steam enters a well-insulated turbine operating at steady state at 4 mpa with a specific enthalpy of 3015.4 kj/kg and a velocity of 10 m/s. the steam expands to the turbine exit where the pressure is 0.07 mpa, specific enthalpy is 2500 kj/kg, and the velocity is 90 m/s the mass flow rate is 17 kg/s neglecting potential energy effects, determine the power developed by the turbine, in kw

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10

Different types of steels contain different elements that alter the characteristics of the steel. for each of the following elements, explain what the element does when alloyed with steel.

Vibration monitoring this technique uses the noise or vibration created by mechanical equipment and in seme cases by plant systems to detemine their actual condtion. a)- true b)- false
