Liquid mercury enters an insulated sudden expansion with a velocity of 1.15 m/s at 20.0°C. The inlet and exit areas are 1.00 × 10-3 and 0.00 × 10-2 m2 , respectively.
Assuming the flow is incompressible and adiabatic, determine the exit temperature and the entropy production rate of the expansion. The specific heat and density of the mercury are 0.1394 kJ/(kg · K) and 13,579 kg/m3 .
