A storage tank for concentrated nitric acid will be constructed from aluminum to resist corrosion. The tank is to have an inside diameter of 6 m and a height of 17 m. The maximum liquid level in the tank will be at 16 m. Estimate the plate thickness required at the base of the tank. Take the allowable design stress for aluminum as 90 N/mm2.
Extract ore descriptors or features from the variables and design a model that can classify the ores correctly from images of the ore
If one of the machines has its field excitation adjusted such that it delivers 125 A lagging current, determine the armature current, power factor, excitation voltage, and power angle of each machine.
A liquid mixture consisting of 100 kmol of 60 mol% benzene, 25 mol% toluene, and 15 mol% o-xylene is flashed at 1 atm and 100°C. (a) Compute the amounts of liquid and vapor products and their composition.
The star point on the primary side of the transformer bank is grounded. The load consists of a heating load of 2 kW per phase and a three-phase induction-motor load of 20 kVA with a lagging power factor of 0.8, supplied at 230 V line-to-line.
Use the following additional information to find the mass transfer flux in the column: mole fraction of ammonia in liquid* 1.351 × 10-3 mole fraction of ammonia in gas* 0.065 total pressure of system 1.013 bar mole mass of ammonia 17 *Note: these ..
What range of flow rates can be achieved if the valve can be throttled down to quarter open? When the valve is quarter open, what fraction of the pump work is lost across the valve?
Calculate the instantaneous and rms values of the voltage induced in a 150-turn coil on the armature, if the axial length of the armature and its inner diameter are both 100 mm.
how many units of x should the firm use?
Two balanced, three-phase, wye-connected loads are in parallel across a balanced three-phase supply. Load 1 draws a current of 20 A at 0.8 power factor leading, and load 2 draws a current of 30 A at 0.8 power factor lagging.
At Chernobyl in 1986, hydrogen was produced by the reaction of superheated steam with the graphite reactor core: C(s)+H2O(g) yields CO(g)+H2(g) It was not possible to prevent a chemical explosion at Chernobyl
Describe the two resulting dimensionless groups (call the dimensionless group for apoptosis A, and the one for the cell cycle B).
The speed of the rotor rotating magnetic field with respect to the stator rotating magnetic field in r/min.
