Superheated ammonia enters an insulated nozzle at 200C and 800kPa. The flow through the low velocity inlet is at 0.015kg/s. At the discharge, the ammonia exits at 280kPa with a velocity of 400m/s. Determine the exit area of the nozzle and the thermodynamic state of the ammonia. (show this also on a P-v/T-v diagram).
When the coal is burned, it produces SO2 emissions which then reacts with calcium dioxide to form solid calcium sulfite. If the coal is burned in a plant that uses 1784 tons of coal per day what is the daily productionof calcium of sulfite in Kg (..
