Apower plant burns 900kg of coal per hour and produces 480kw of power. if each kg of coal releases 5,9mj, determine the efficiency of the plant
b)air enters the nozzles at 3,0 bar, 1270c and 30m/s. during its passages a heat loss of 4,40kj/kg and the fluid leaves at 2,0 bar and 270m/s. the heat loss to environment ioccurs at 270c. calculate the final temperature, the entropy change of air and the total entropy change of the overall process, is the process reversible, irrevessible or impossible?
