A50-m-long section of a steam pipe whose outer diameter is 10 cm passes through an open space at 15 °c. the average temperature of the outer surface of the pipe is measured to be 150 °c, and the combined heat transfer coefficient on the outer surface of the pipe is 20 w/m2.°c, determine tair = 15°c 150°c steam 50m fiberglass insulation (a) first calculate the rate of heat loss from the steam pipe if there is no insulation. (b) now determine the thickness of fiberglass insulation (k = 0.035 w/m·°c) needed in order to save 90 percent of the lost heat. assume the pipe temperature remains constant at 150 °c

answer:

science is the study of the nature and behavior of natural things and the knowledge that we obtain about them. a science is a particular branch of science such as physics, chemistry, or biology. physics is the best example of a science which has developed strong, abstract theories.

pseudoscience is a collection of beliefs or practices mistakenly regarded as being based on scientific method.
