A spherical container of inner radius of 0.44 m and outer radius of 0.6 m with a thermal conductivity 18 W/m·K holds radioactive waste that generates heat at 1 x 105 W/m3. The outer surface is exposed to a water flow with [infinity] 25°C and 750 W/m2·K. Find the heat transfer through the wall of container as well as the temperatures at the inside and outside surfaces of the container

Which one from below is not one of the reasons of planning failures? (clo3) a)-planner is careless. b-planner spend less time in the field but more time on the desk c)-planner is not qualified d)-planner does not have sufficient time to properly plan

The flow rate of air through a through a pipe is 0.02 m5/s. a pitot static tube is placed in the flow. the radius of the pitot static tube is 1 mm. assuming the flow to be steady and the air to be at 300k, calculate the difference in total and static pressure if the diameter of the pipe is: (a) d 0.1 m d 0.05 m (c) d 0.01 m

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?
