1.Determine the settling rate of fly ash particles entering the smokestack of a municipal incinerator. Average particle size has been found to be 5.0 µm and the temperature of the stack exhaust gases is 750 oC. Confirm your analysis
2.Show that the Mach number is proportional to the square root of the ratio of the inertial force to the elastic force.
Hint: The elastic force involves the bulk modulus E
3.The flowrate Q over a rectangular sharp crested weir depends on the width of the notch b, the head on the weir H, and the acceleration due to gravity g.
Find how many dimensionless parameters govern this problem. Use dimensional analysis to find the relationship.
