Steam flows steadily through an adiabatic turbine. the inlet conditions of the steam are 4 mpa, 500°c, and 80 m/s, and the exit conditions are 30 kpa, 92 percent quality, and 50 m/s. the mass flow rate of the steam is 12 kg/s. determine (a) the change in kinetic energy, (b) the power output, and (c) the turbine inlet area.

Edward tolman explained the results of his study by theorizing that the rats were learning about the maze during every trial but they a. were agitated because other groups were getting reinforcement b. could not remember how to demonstrate it without reinforcement c. were not motivated to demonstrate it without reinforcement d. seemed to be too lazy to actually work without reinforcement
