(b) Partially condensed steam with a mass flow rate of 4kg/s consists of 4% steam and 96% of water by mass. The steam exits a heat exchanger where it passes through a 3m long and 50mm diameter of smooth pipe at a mean temperature of 320K and pressure 130kN/m2. Assume the steam follows an ideal gas law and the viscosity of the steam and water at the given temperature and pressure are 1.13105Ns/m2 and 5.20104Ns/m2, respectively. Determine the flow type in both phases (water and steam). (Density of steam =0.788kg/m3, Density of water =1000kg/m3, Gas constant, R=8.314kN/kgmol.K ) (9 marks)
