Document Summary

Me 235 thermodynamics i / winter 2014 / section 002. 4. 83 the main waterline into a tall building has a pressure of 600 kpa at 5 m below ground level. A pump brings the pressure up so the water can be delivered at 200 kpa at the top floor 100 m above ground level. Assume a flow rate of 10 kg/s liquid water at 10 c and neglect any difference in kinetic energy and internal energy u. 4. 87 a steam turbine receives steam from two boilers. One flow is 5 kg/s at 3 mpa, 700 c and the other flow is 10 kg/s at 800 kpa, 500 c. The exit state is 10 kpa, with a quality of 96%. Find the total power out of the adiabatic turbine. 4. 88 a compressor receives 0. 1 kg/s r-134a at 150 kpa, -10 c and delivers it at 1000 kpa, 40 c. The power input is measured to be 3 kw.
