23m3/hr of air at 600kPa,330K enters a well-insulated, horizontal pipe having a diameter of 1.2cm and exits at 120kPa. Assume steady state and use the ideal gas model for the air. Also assume constant specific heat, c=1.007kJ/kgK for air at 330K. Determine the mass flow rate, in kg/s, and the exit velocity, in m/s. Step 1 Determine the mass flow rate, in kg/s. m1=kg/s Step 2 Determine the exit velocity, in m/s. v2=
