Pressurized steam at 540 k flows through a long, thin-walled pipe of 0.6-m diameter. the pipe is enclosed in a concrete casing that is of square cross section and 2 m on a side. the axis of the pipe is centered in the casing, and the outer surfaces of the casing are maintained at 300 k. what is the heat loss per unit length of pipe?

Describe one experiment in which the glass transition temperature and melting temperature of a totally amorphous thermoplastic material can be determined. show the relevant experimental results in a diagram which should be properly annotated with the two temperatures clearly marked. what is likely to happen to the curve in the diagram if the amorphous polymer is replaced by a thermosetting type?

What are the major differences between injection molding and extrusion?

An engine, weighing 3000 n, is supported on a pedestal mount. it has been observed that the engine induces vibration into the surrounding area through its pedestal at the maximum operating speed. determine the stiffness of the dynamic vibration absorber spring in (n/m) that will reduce the vibration when mounted on the pedestal. the magnitude of the exciting force is 250 n, and the amplitude of motion of the auxiliary mass is to be limited to 2 mm note: in this question type-in right numbers, no decimals, no fractions, no unit. approximate to right number if needed
