Question 2 Oil at 20C (s.g 0.869, p = 8.14 x 10-2) is to flow through a 200 m long horizontal concrete pipe (e = 0.3 mm). What size pipe will carry 0.012 m/s with a pressure drop due to friction of 15 kPa? (Maximum 3 iterations). [20] Question 3 CO2 enters a constant area duct at the temperature of 172C, pressure of 690 kPa, and the flowrate of 548.64 km/hr. Further downstream the properties change to 304.8 m/s and 505C. calculate: 3.1. Pressure (P2) at section 2 The change in enthalpy between sections (3) (3) 3.2
