Heat is generated in a cylindrical fuel rod in a nuclear reactor according to the relationship ˙ q = ˙ q max [ 1 − ( r r o ) 2 ] q˙=q˙max[1−(rro)2] where ˙ q q˙ is the volumetric heat generation rate, kw/m3, and ro is the outside cylinder radius. develop the equation that expresses the temperature difference between the rod center line and its surface.

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.

Coiled springs ought to be very strong and stiff. si3n4 is a strong, stiff material. would you select this material for a spring? explain.
