Self-insurance is being considered for one portion of a chemical company. The fixed-capital investment involved is $50,000, and insurance costs for complete protection would amount to $400 per year. If self-insurance is used, a reserve fund will be set up under the company's jurisdiction, and annual insurance premiums of $300 will be deposited in this fund under an ordinary annuity plan. All money in the fund can be assumed to earn interest at a compound annual rate of 5 percent. Neglecting any charges connected with administration of the fund, how much money should be deposited in the fund at the beginning of the program in order to have enough money accumulated to replace a complete $50,000 loss after 10 years?
The mole fraction of ammonia in exit gas from the tower is 0.003. Assuming isothermal operation and considering the following equilibrium data calculate the height of the packed bed.

What must be the area of a parallel plate capacitor, with plates separated a distance d = 0.01 mm and relative permittivity of 4 for the dielectric between the plates to supply the same charge as the battery in (a)?
Consider the solution of Example 11.4.1. By means of a phasor diagram, determine the load power factor for which the regulation is maximum (i.e., the poorest), and find the corresponding regulation.
Determine whether the claimed performance of the process is consistent with the second law. Assume that air is an ideal gas for which Cp = (7/2)R.
From the magnetic moment of 1.7 μB per Co in metallic Co, predict what Ms will be. Note that a unit cell of Co contains 6 atoms, and has a volume of 6.68×10-2nm3.Ms (in kA/m):
In the manufacture of methyl ethyl ketone from butanol, the product is separated from unreacted butanol by distillation. The feed to the column consists of a mixture of 0.90 mol fraction MEK, 0.10 mol fraction 2-butanol, with a trace of trichloroe..
In the method of virtual work, there is no work performed. Only the possibility, or the inference of work. Explain the physical process behind the method.
A patient is exercising his shoulder extensor muscles with wall pulleys (Fig. 5.8). Weights of 20, 10, and 5 lbs are loaded on the weight pan, which weighs 4 lbs. The patient is able to exert 45 lbs on the pulley. What is the resultant force of th..
