A part produced from a 4320 steel has a hardness of HRC 35 at a critical location after quenching. Determine
(a) the cooling rate at that location, and
(b) the microstructure and hardness that would be obtained if the part were made of a 1080 steel.
1. (a) In your own words describe briefly the phenomenon of luminescence. (b) What is the distinction between fluorescence and phosphorescence?
Consider a 1.25 cm diameter carbon steel (1% C, k = 40 W/m-K) sphere to be cooled from 500oC to 100oC by a cooling air flow at 25oC with convection coefficient of 110 W/m2-K.
What would be the procedure for producing uniform workplace illuminance when both sidelighting and skylighting are used simultaneously?
what is value of convective heat transfer coefficient for pebble glass in air medium?
A bioengineer is trying to determine the amount of gap developed between bone and cement when a femoral hip is placed. The system is assumed to consist of concentric cylinders. Calculate the gap developed between bone and cement if the temperatures o..
