25 m3/hr of air at 600 kPa, 330 K enters a well-insulated, horizontal pipe having a diameter of 1.2 cm and exits at 120 kPa. Assume steady state and use the ideal gas model for the air. Also assume constant specific heat, c = 1.007 kJ/kg·K for air at 330K.

Determine the mass flow rate, in kg/s, and the exit velocity, in m/s.
