What is the relationship between screens, screen schemes and issue type screen schemes?
how are they related to field configurations?
how do you determine the maximum number of screens possibly used in a project (for issue operations and workflow transitions)?
who can make changes to screens, screen schemes and issue type screen schemes?

Along steel shaft of 10 cm diameter is austenised at 870°c and then quenched in a liquid at 30oc. the average surface heat transfer coefficient is 2000 w/m2. °c. the relevant thermophysical properties of the shaft are: p=7800 kg/m", k=20 w/mk, cp=0.46 kj/kg.k calculate: a)-the time required for the center temperature to drop to 200°c. b)-the temperature at half-radius at that moment. c)-the amount of heat that had been transferred to the liquid by that time per meter length of the shaft
