1. Determine the mass flow rate of steam required to produce 750 kW output in a turbine where potential and kinetic energy changes are negligible. The steam enters at 1 MPa and 250oC and leaves at 200 kPa and a quality of 92%.
2. A steam turbine operates with inlet conditions of 10 MPa, 500oC, and a velocity of 80 m/s. Dry saturated steam leaves the outlet at 0.1 MPa at a velocity of 160 m/s. The datum level is taken at the outlet and the elevation of the inlet is at 2 m. The heat loss through the turbine casing is 40 kW and the mass flow rate is 2 kg/s. Determine
(a) the power delivered by the turbine and
(b) the power delivered by the turbine if potential and kinetic energy changes are negligible.
Find the PSD of the waveform out of an r = 0.5 raised cosine-rolloff channel when the input is a polar NRZ signal. Assume that equally likely binary signaling is used and the channel bandwidth is just large enough to prevent ISI.
