An object whose mass is 330.693 lb experiences changes in its kinetic and potential energies owing to the action of a resultant force R. The work done on the object by the resultant force is 163 Btu. There are no other interactions between the object and its surroundings. If the object’s elevation increases by 90 ft and its final velocity is 150 ft/s, what is its initial velocity, in ft/s? Let g = 32.2 ft/s^2. Ans. V1 = 60.10 ft/s
Carbon dioxide (CO2) fills a closed, rigid tank fitted with a paddle wheel, initially at 80°F, 50 lbf/in2, and a volume of 2.2 ft3. The gas is stirred until its temperature is 500°F. During this process heat transfer from the gas to its surroundings occurs in an amount 2.6 Btu. Assume ideal gas behavior, but do not assume constant specific heats. Kinetic and potential energy effects can be ignored. Determine the mass of the carbon dioxide, in lb, and the work, in Btu.
