A process plant making 2000 tons per year of a product selling for $0.80 per lb has annual direct production costs of $2 million at 100 percent capacity and other fixed costs of $700,000. What is the fixed cost per pound at the break-even point? If the selling price of the product is increased by 10 percent, what is the dollar increase in net profit at full capacity if the income tax rate is 34 percent of gross earnings?
Give one method of elemental analysis by electron microscopy. What is the underlying physical principle, and how is it specific to each element?
If the feed includes 0.5 mol of steam (an inert diluent) per mole of ethane and if the reaction reaches equilibrium at 1100 K and 1 bar, what is the composition of the product gas on a water-free basis?
Does this distribution fit a normal distribution curve?
If the torque lost due to friction and wind age is 7% of the shaft torque, calculate the developed torque.
Following a procedure analogous to that in Example 5.2, obtain an expression for the coefficient of thermal expansion based on the van der Waals equation of state. Use the result to calculate the value of β for oxygen at 20 °C, 30 bar.
A stylized 108 saccade is shown in the following figure. Estimate z and n for the Westheimer model described in Section 12.4. Calculate the time to peak velocity and peak velocity
Neglecting stator resistance, leakage reactance, and all losses, if the stator-to-rotor turns ratio is 2:1 and the applied voltage is 100 V, find the rotor-induced emf at standstill and at 0.05 slip.
A stream of ethane gas at 493.15 K (220°C) and 30 bar expands isentropically in a turbine to 2.6 bar.
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.
Develop an answer to each of the following explosive related questions, using at least 200 words total for parts a and b. Paraphrased and/or quoted materials must have accompanying in-text and reference citations in APA format.The DOT regulation at 4..
We can use z-transforms to find the sum of integers raised to various powers. This is accomplished by first recognizing that the sum is the solution of the difference equation
