25 um particles with a density of 2500 kg/m are suspended in a liquid with a density of 1000 kg/m at a concentration of 40 kg/m? Assuming 1 m of suspension, calculate the solids volume fraction and bulk density (Paw) of the suspension.
Compute the volume percent of graphite VGr in a 3.8 wt% C cast iron, assuming that all the carbon exists as the graphite phase. Assume densities of 7.9 and 2.3 g/cm3 for ferrite and graphite, respectively. Answer in Vol%
Tooling for a vacuum deposition system is cleaned and reassembled. Unfortunately, a drop of water 0.125 cm3 in volume is left in the bottom of a screw hole. Due to the obstructed path to the pump, a negligible amount of water escapes during the early stages of pumpdown, and the drop becomes a virtual leak at a chamber pressure of 4.3E-06 torr. Find the volume of gas formed by the water at this pressure (assume it stays at room temperature). The density of water is 1g cm-3 and the molecular weight 18 g mole-1. (First, determine the number of moles in the drop of water, and use the ideal gas law to determine the volume)(b) To make this result clearer, what is the added time (in hours) to pump out this chamber due to this droplet if the pump, at that pressure, has a rate of 1480 L/s?

3. Determine the porosity of a sweet Vidali onion, which is composed of 93.8% water, 1.04% protein, 0.45% fat, 4.48% carbohydrate, and 0.46% ash. The apparent density of the onion was measured by the liquid displacement method. Toulene was used as the pycnometer liquid. All the measurements were carried out at 20°C and the density of the toluene at that temperature is known to be 865 kg/m³. The date obtained from liquid displacement measurements are: Weight of the empty pycnometer: Weight of the pycnometer filled with toluene: Weight of the pycnometer containing only onion: Weight of the pycnometer containing the onion and toluene: 75.87 g 126.58 g 85.87 g 127.38 g
Barium titanate, a ceramic used in electronics, was analyzed by the following procedure: Into a Pt crucible was placed 1.2 g of Na₂CO3 and 0.8 g of Na₂BO7 plus 0.3124 g of unknown. After fusion at 1000°C in a furnace for 30 min, the cooled solid was extracted with 50 mL of 6 M HCl, transferred to a 100-mL volumetric flask, and diluted to the mark. A 25.00-mL aliquot was treated with 5 mL of 15% tartaric acid (which complexes Ti4+ and keeps it in aqueous solution) and 25 mL of ammonia buffer, pH 9.5. The solution was treated with organic reagents that complex Ba²+, and the Ba complex was extracted into CC14. After acidification (to release the Ba²+ from its organic complex), the Ba²+ was back-extracted into 0.1 M HC1. The final aqueous sample was treated with ammonia buffer and methylthymol blue (a metal ion indicator) and titrated with 32.42 mL of 0.01376 M EDTA. Find the weight percent of Ba in the ceramic. weight percent of Ba: wt%

Hot mix asphalt (HMA) is commonly used in the construction of roadways in the United States at a rateestimated to be 500,000,000 tons/year. A typical upper layer (there may be as many as 5 layers ofdifferent thicknesses and compositions) of a high-volume highway is composed of crushed stone (alsoknown as crushed aggregate) and asphalt binder and is approximately 1.25 inches thick. The stone,which has a specific gravity of about 2.7, is mixed with asphalt binder (SG = 1.03) to form the HMAwith a composition of approximately 95 wt% aggregate and 5% asphalt. What is the volume ft3 of asphalt binder and weight (tons) of HMA required for the top layer of a 15-mile segment of interstatehighway with 5 lanes, each of which has a width of 12 ft?
