Air enters a sudden contraction in a pipe at a rate of 0.300 lbm/s. The contraction coefficient is 0.470, the exit temperature is 156°F and the exit diameter is 2.00 in. The pipe is insulated. The pressure across the contraction drops from 185 to 50.0 psia.

Determine the entrance temperature and the entropy production rate of the contraction. Assume the air to be an ideal gas with constant specific heats.
