A trаnsitiоn sectiоn is plаced in а rectangular air duct as shоwn in the figure. Air flows steadily through the duct at a mass flow rate of: m˙=2.5 kg/sdot{m} = 2.5 , text{kg/s} Assuming steady flow and neglecting losses, determine the pressure change that occurs between the two ends of the transition. Take the density of air as: ρa=1.23 kg/m3rho_a = 1.23 , text{kg/m}^3 Show all work to determine your answer.
