Carbon dioxide enters an adiabatic compressor at 100 kpa and 300 k at a rate of 1.8 kg/s and exits at 600 kpa and 450 k. neglecting the kinetic energy changes, determine: (a) the isentropic efficiency of the compressor.

Steel is coated with a thin layer of ceramic to protect against corrosion. what do you expect to happen to the coating when the temperature of the steel is increased significantly? explain.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
