Document Summary
Professor: dr. b. kruczek: open textbook / class notes examination, the examination consists of two parts: Part a (40%) attempt 2 questions out of 3, each worth 20 marks. Part b (60%) attempt 2 questions out of 3, each worth 30 marks: state clearly all assumptions, it is strongly recommended to describe in words the outline of your solution. Part a 40% attempt 2 of the following 3 questions. A thermocouple, which is initially at 20oc, is inserted in a stream of hot gas at te. After 3 seconds the thermocouple reads 80oc while after 6 seconds it reads 110oc. Assuming applicability of the lumped thermal capacity model, estimate the temperature of the hot gas. What would be the temperature of the thermocouple after 10 seconds in the hot gas stream? ln = x ax a ln. A saturated low-pressure steam flows through two thin-walled pipes of diameters da = 5 cm and.
