There is a system with steam that enters an adiabatic compressor at a steady flow rate of 22.0 kg/s at 50.0 kPa, 150.0 °C, and 12 m/s, and leaves at 5.00 MPa, and 75 m/s. If the power input to the compressor is 1.20 MW determine: (a) the exit temperature of the steam, and
(b) the area of the compressor inlet.

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.

Abrake has a normal braking torque of 2.8 kip in and heat-dissipating cast-iron surfaces whose mass is 40 lbm. suppose a load is brought to rest in 8.0 s from an initial angular speed of 1600 rev/min using the normal braking torque; estimate the temperature rise of the heat dissipating surfaces.

Fluids at rest possess no flow energy. a)- true b)- false
