Two rods, one of butadiene rubber (BR) and one of high-density polyethylene (HDPE), are rigidly connected in series. The BR rod is 1m long with a diameter of 10mm, while the corresponding dimensions for the HDPE rod are 0.8m and 5mm, respectively. Let the tensile modulus for BR be 1.6Mpa and the corresponding value for HDPE= 0.7Gpa. Determine the final length of the rod when a weight of 3kg is applied in tension.
The following four solvents, with accompanying distribution coefficients in mass-fraction units, are being considered. Water and each solvent (C) can be considered immiscible. For each solvent, estimate the kilograms required per hour if a single ..
Design the manufacture of (tones/day) Ferrous sulphate monohydrate from waste pickle liquor. Pickling is generally associated with the removal of scale with mineral acid. Sulphuric acid is the most commonly used pickling acid.
Fresh rainwater or surface water contains enough tritium ( ) to show 5.5 decay events per minute per 100. g of water. Tritium has a half-life of 12.3 years. You are asked to check a vintage wine that is claimed to have been produced in 1946.
Carry out a sensitivity analysis on the adipic acid project described in Example 9.5. Investigate the sensitivity of the 10-year NPV to variation in total fixed capital (-20% to +50%), annual gross profit (-20% to +30%), and project construction s..
Methanol can be manufactured by the gas phase reaction CO(g) + 2H2(g)?CH3OH(g)at 400K and 1.013 bar.The following data are available;?H298= -90.71 kJ/mol?G298= -24.33 kJ/mol.
The viscosity of the liquor is 0.7 mN m-2 s. The cutoff crystal size required is 5 μm. Select a suitable type of centrifuge to use for this duty.
An electronics plant uses an adsorption system to recover solvent from a vent gas stream and prevent volatile organic compound (VOC) emissions. The vent gas flow rate is 20 m3 /s of dry air at 293 K, 1.5 atm.
A spherical ball of benzoic acid (diameter = 1.5 cm) is submerged in a pool of still water. The solubility and diffusivity of benzoic acid in water are 0.03 kmol/m3 and 1.25 x 10-9 m2/srespectively.
in heat transfer terms , the surface temperature rises above the wet bulb surface ceases to behave as a wet surface - the surface temperature rises to dry bulb temperature and air as the moisture level fa..
What are the major drivers and forces of Australia's economy, such as major cities, major products and manufacturing locations, where raw materials come from, and transportation networks that have either created corridors or barriers to economic d..
Which of the following would you expect to be elastomers and which thermosetting polymers at room temperature? Justify each choice.
