1. (a) Explain Herring's scaling law in solid state sintering and describe important points to be considered in its application to real systems.
(b) Derive the scaling law for the evaporation/condensation mechanism.
2. Which process, above all, controls sintering achieved by the evaporation/ condensation mechanism?
The overall heat transfer coefficient based on the gas-side surface area is Uh 100 W/m2 · K. Determine the required gas-side surface area Ah using the NTU method.
suppose a heat engine is connected to two energy reservoirs one apool of molten aluminum 660degc and the other a block
At what equivalence ratio for octane-air mixtures does the carbon to oxygen ratio of the system equal one? Why is this of interest?
steam at 1.6mpa and 400 degrees c is contained in a rigid box. the system is then cooled to 200 degrees c. compare the
Refrigerant 134a enters a 28-cm diameter pipe steadily at 200 kPa and 200C with a velocity of 5 m/s. The refrigerant gains heat as it flows through the pipe and leaves the pipe at 180 kPa and 400C. Determine the volumetric flow rate of the refrigeran..
Find the stiffness of each spring when a refrigerator unit having a mass of 30 kg is to be supported by three springs. The force transmitted to the supporting structure is only 10% of the impressed force. The refrigerator unit operates at 420 rpm.
Design the number of teeth and depth of teeth need be chosen. Considerations include the turn angle for each stroke, the bearing stress on the teeth and pins and shear stress on the teeth.
