Carbon monoxide (CO) enters a nozzle operating at steady state at 25 bar, 2578C, and 45 m/s. At the nozzle exit, the conditions are 2 bar, 578C, 560 m/s, respectively. The carbon monoxide can be modeled as an ideal gas.
(a) For a control volume enclosing the nozzle only, determine the heat transfer, in kJ, and the change in specific entropy, in kJ/K, each per kg of carbon monoxide flowing through the nozzle. What additional information would be required to evaluate the rate of entropy production?
(b) Evaluate the rate of entropy production, in kJ/K per kg of carbon monoxide flowing, for an enlarged control volume enclosing the nozzle and a portion of its immediate surroundings so that the heat transfer occurs at the ambient temperature, 278C.
An ordinary egg can be approximated as a 5.78 cm diameter sphere. The egg is initially at a temperature of 7.9C and is dropped into boiling water at 97C. Taking the properties of the egg to be p=1020 and cp=3.32. Determine how much heat is transferre..
