Arankine cycle with one closed feedwater heater with its drain cascaded backward has a water mass flow rate through the steam generator of 140 kg/s. superheated steam enters the turbine system at 19.3 mpa and 5408c, and saturated liquid water exits the condenser at 28 kpa absolute. the closed feedwater heater receives extracted steam from the turbine at 2.4 mpa absolute, and the temperature of the feedwater exiting the closed feedwater heater is 2108c. determine the net power produced by the cycle and the thermal efficiency of the cycle if (a) the turbine and pump are isentropic, and (b) the turbine isentropic efficiency is 0.82 and the isentropic efficiencies of the pump is 0.65.

An alligator swims to the left with a constant velocity of 5 \,\dfrac{\text{m}}{\text s}5 s m ? 5, space, start fraction, m, divided by, s, end fraction. when the alligator sees a bird straight ahead, the alligator speeds up with a constant acceleration of 3 \,\dfrac{\text {m}}{\text s^2}3 s 2 m ? 3, space, start fraction, m, divided by, s, start superscript, 2, end superscript, end fraction leftward until it reaches a final velocity of 35 \,\dfrac{\text {m}}{\text s}35 s m ? 35, space, start fraction, m, divided by, s, end fraction leftward. how many seconds does it take the alligator to speed up from 5 \,\dfrac{\text {m}}{\text s}5 s m ? 5, space, start fraction, m, divided by, s, end fraction to 35 \,\dfrac{\text {m}}{\text s}35 s m ? 35, space, start fraction, m, divided by, s, end fraction?
