A well-insulated rigid vessel of volume 0.2 m^3 is divided into two equal compartments by thin diaphragm, as illustrated in the accompanying figure. One of the compartments is a vacuum. The other is a fluid at a pressure of 200 kPa and a temperature of 125 degrees Celsius. The diaphragm is ruptured and fluid fills the entire volume of the vessel. Assume that the fluid is an ideal gas. After you have determined Qsub12, Wsub12, and delta U for the process, calculate the final temperature of the gas.
The company will use an annual interest rate of 10%. Annual maintenance and pumping costs may be considered to be paid in their entireties at the end of the years in which their costs are incurred.
Starting from rest, the boy runs outward in the radial direction from the center of the platform with a constantacceleration of 0.5 m/s2. If the platform is rotating ata constant rate θ=0.2 rad/s,
The cost of running this fleet is $325/hr per truck. For a given contract, a total of 2,500 tons must be removed from one construction site and moved to another location 35 miles away.
For FCC diamond cubic structures, give the lattice coordinates for the atoms found in the [100], [110], [111] direction? and Calculate the linear density of atoms in these directions for Ge.
Oil (specific gravity 0.752) flows through a 6" horizontal pipe under a pressure of 60 psi. Assuming no losses, what is the flow in cfs if the pressure at a 3" diameter reduction is 20 psi
Assume that the interfacial tension between oil-water is 22 dynes/cm and the contact angle through water is 93
A small truck is to be driven down a 4% grade at 70mi/hr. The coefficient of road adhesion is 0.95, and it is known that the baking efficiency is 80% when the truck is empty and decreases by one percentage point for every 100 lb of cargo added.
The magnetic declination of 1986 was 5 degrees 15 minutes. The magnetic bearing of a line was N 89 degrees 49 minutes W. At todays present the magnetic bearing of a line is S 88 degrees 20 minutes W.
