12 a nuclear power plant based on the rankine cycle operates with a boiling-water reactor to develop net cycle power of 3 mw. steam exits the reactor core at 100 bar, 52o degree c and expands through the turbine to the condenser pressure of 1 bar. saturated liquid exits the condenser and is pumped to the reactor pressure of l00 bar. isentropic efficiencies of the turbine and pump are 81% and 78%, respectively. cooling water enters the condenser at 15 degree c with a mass flow rate of 114.79 kg/s. determine (a) the thermal efficiency. (b) the temperature of the cooling water exiting the condensor in degree c.

The rigid beam is supported by the three suspender bars. bars ab and ef are made of aluminum and bar cd is made of steel. if each bar has a cross-sectional area of 450 mm2, determine the maximum value of p if the allowable stress is (σallow)st = 200 mpa for the steel and ( σallow)al = 150 mpa for the aluminum. est = 200 gpa and eal = 70 gpa.

These models show the electron structures of two different nonmetal elements. which element is likely more reactive, and why? element 1 is more reactive because it has fewer electron shells and is toward the top of its group on the periodic table. element 1 is more reactive because it has more electrons in its valence shell and is farther to the right on the periodic table. element 2 is more reactive because it does not have a valence shell close to the nucleus, so it will attract electrons. element 2 is more reactive because it does not have a full valence shell, so it will attract electrons.
