Unformatted text preview: ENGRD 221: ENGINEERING THERMODYNAMICS Problem Set 5 Due February 27th, 2009 (5 Questions) Question 1 (4.102): A simple steam power plant operates at steady state with water circulating through the components with a mass flow rate of 60kg/s. Figure 1 shows additional data at key points in the cycle. Stray heat transfer and kinetic and potential effects are negligible. Determine (a) the thermal efficiency and (b) the mass flow rate of cooling water though the condenser, in kg/s. Figure 1 Question 2 (5.18): A power cycle receives energy QH by heat transfer from a hot reservoir at TH=1500oR and rejects energy QC by heat transfer to a cold reservoir at Tc = 500oR...
