Steam at 320°c flows in a stainless steel pipe (k 515 w/m·k) whose inner and outer diameters are 5 cm and5.5 cm, respectively. the pipe is covered with 3-cm-thickglass wool insulation (k 5 0.038 w/m·k). heat is lost to thesurroundings at 5°c by natural convection and radiation, witha combined natural convection and radiation heat transfercoefficient of 15 w/m2·k. taking the heat transfer coefficientinside the pipe to be 80 w/m2·k, determine the rate of heatloss from the steam per unit length of the pipe. also determinethe temperature drops across the pipe shell and the insulation.

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 11.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.80 m/s; (b) he is then lifted at the constant speed of 4.80 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 78.0 kg rescue by the force lifting him during each stage

Which lists the organs in the correct order as food passes from the mouth to anus?

As part of your daily workout, you lie on your back and push with your feet against a platform attached to two stiff springs arranged side by side so that they are parallel to each other. when you push the platform, you compress the springs. you do an amount of work of 79.0 j when you compress the springs a distance of 0.230 m from their uncompressed length. (a) what magnitude of force must you apply to hold the platform in this position? (b)how much additional work must you do to move the platform a distance 0.230 m farther? (c) what maximum force must you apply to move the platform a distance 0.230 m farther?
