Question

problem 1 1) A stream of 21,000 kg/h of steam flows steadily through of a turbine, entering at 3.5 MPa, 500 °C, and leaving at 50 KPa, with a quality of 85%. A heat loss of 22 kJ/kg occurs. The inlet tube has a diameter of 11 cm, and the outlet section is rectangular. With dimensions of 0.55 and 0.65 m. Part I) Determine 1) The change in kinetic energy. 2) The properties of state 1 (v₁; h₁; u₁; S₁; P₁; T₁) 3) the properties of state 2 (V₂: h2;U₂; Sai Pai T₂. 4) The change of: specific volume, internal energy, enthalpy, entropy. 5) power output. 6) The change of entropy of the system. 7) Find the entropy of the surroundings if T= 28°.8) Find the total change in entropy. Part II) Make the diagrams of P-v, T-v and T-s, indicating the values of the properties.
