6–18 A steam power plant receives heat from a furnace at a rate of
... rate of 280 GJ/h. Heat losses to the surrounding air from the steam as it passes through the pipes and other components are estimated to be about 8 GJ/h. If the waste heat is transferred to the cooling water at a rate of 145 GJ/h, determine (a) net power output and (b) the thermal efficiency of this ...

performances of flat-plate and cpc solar collectors in underfloor
... Collector (CPC) collectors to replace Flat-Plat collectors in solar energy underfloor heating systems. By this way, it is aimed to explore the feasibility of area reduction required by the collectors. Secondly, the temperature profiles of the circulating water loops and the concrete slabs are sought ...
