The figure shows a pipe connected a tee-section. Water with density of 1000 kg/s flows steadily from section 1 towards sections 2 and 3. At section 1, the area is 0.08 m^2 and the internal energy is 120 J/kg. At section 2, the area is 0.03 m^2, the velocity is 4.5 m/s, the gage pressure is zero and the internal energy is 130 J/kg. At section 3, the area is 0.05 m^2 the velocity is 4.5 m/s and the internal energy is 135 J/kg. If viscous effects, gravity and potential energy are negligible. Consider the atmospheric pressure 101 kPa. Answer the following questions.
