Asteam turbine has steam flowing at steady rate of 5 kg/s entering at 5 mpa and 500 °c and leaving at 2 mpa and 140 °c. during flow through turbine a heat loss of 600 kj/s occurs to the environment at 1 atm ad 25 °c. determine 1) the availability of steam at inlet to turbine ii) the turbine output iii) the maximum possible turbine output, and iv) the irreversibility you may neglect changes in kinetic energy and potential energy during flow.

On a average work day more than work place firs are reorted

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.

Acertain flow of air (at stp) has a velocity distribution given by v i (in ft/s). if this flow is going through a 4 ft square area in the yz-plane (centered at the origin), what is the mass flow rate (in lbm/s)?
