2. 2.7 kg/s of water enters an adiabatic device at 400 psia and 350 F, 1266 ft/s and at a height of 4.7 ft. Water leaves the device at 566.1 ft/s, 162 psia, 800 F and at a height of 16 inches. Water is also being added (or removed) to the device at an intermediate location (between the inlet and outlet) with the following properties: 10 psia and 1200 F. Can you find the work output from (or input to) the device in hp if the entropy of the universe in the process is 4 kW/K and if the surroundings are at 1800 R. What is the diameter of the pipe at the entrance in inches? What is the amount of water that is being added (or removed) at the intermediate location in kg/s? 2. 2.7 kg/s of water enters an adiabatic device at 400 psia and 350 F, 1266 ft/s and at a height of 4.7 ft.
