Determine the maximum amount of work obtainable in a flow process from 1 kg of steam at 3000 kPa and 723.15 K (450°C) for surrounding conditions of 300 K and 101.33 kPa.
Calculate the molarity of each of the following aqueous solutions. a. 5.0 ppb Hg in H2O b. 1.0 ppb CHCl3 in H2O c. 10.0 ppm As in H2O d. 0.10 ppm DDT (C14H9Cl5) in H2O
Isophthalic acid (IPA, formula HOOC-C6H4-COOH) is made by oxidation of m-xylene with air. The reaction is carried out in acetic acid solvent at about 200 °C using a cobalt-manganese catalyst promoted by bromine.
A condenser is required to condense n-propanol vapour leaving the top of adistillation column. The n-propanol is essentially pure, and is a saturated vapourat a pressure of 2.1 bara.
During the research that led to production of the two atomic bombs used against Japan in World War II, different mechanisms for obtaining a supercritical mass of fissionable material were investigated.
Calculate the excess enthalpy of mixing for a solution that contains 60% by mol hydrazine at 20 °C.
If you dropped in a piece of magnesium, the magnesium would disappear and hydrogen gas would be released. Represent this change using symbols for the elements, and write out the balanced equation.
Experimental tests have been carried out on this equipment, and the results for the slurry mixture used can be expressed as follows for any one pressure drop:
At a power angle of 30°, the power developed by the motor is 33 kW. Determine the reactive kVA of the motor, and the overall power factor of the motor and the load.
For the design of internal-pressure cylindrical vessels, the API-ASME Code for Unified Pressure Vessels recommends the following equations for determining the minimum wall thickness when extreme operating pressures are not involved:
Estimate the area under the curve f(x) = 16 - x^2 from x = 0 to x = 3 by using three inscribed (under the curve) rectangles. Answer to the nearest integer.
Determine the temperature and phase of water from the following information. If the phase is a vapor-liquid mixture, report the fraction of vapor and liquid.
