A well-insulated turbine operating at steady state develops 28.75 MW of power for a steam flow rate of 50 kg/s. The steam enters at 25 bar with a velocity of 61 m/s and exits as saturated vapor at 0.06 bar with a velocity of 130 m/s.
Neutrons of 1.5 MeV energy are introduced at the rate of 2x10^15 neutrons/cm^3/sec into an infinite slab of graphite. Calculate the number of elastic scattering collisions occurring per second per cm^3 in the energy interval from 0.5 to 0.3 MeV. C
