1.A standard reverse-flow cyclone with a length of 5cm has a cut diameter of 250 microns. at a flow rate of 10^-7 m^3/s, what would the diameter corresponding to 90%removal be?
2.Water, initially dry saturated vapour at 4 bar, lls a closed rigid con- tainer. The water is heated until its temperature is 400C. Determine the work done and the heat transfer.
3.What is the elongation of a rectangular bar (cross section 2 inch * 2 inch length 4 ft) When it is subjected to an axial load of 80,000 lbs. Assume the material of the bar has the following properties G = 7,700 KSI, V =0.30
