1. Ammonia is initially at a temperature of -10° C and a specific volume of 0.07 m3/kg. The ammonia undergoes an isobaric expansion to a final specific volume of 0.22 m3/kg. Evaluate the specific work done on the ammonia in kJ/kg and the specific heat transfer to the ammonia in kJ/kg. Neglect changes in kinetic energy and potential energy.

2. Carbon dioxide is contained in a piston-cylinder assembly with an initial pressure and temperature of 8 lbf/in2 and 100° F, respectively. The carbon dioxide has a mass of 0.05 lb. The carbon dioxide is expanded isothermally to a final volume of 1 ft3. Model the carbon dioxide as an ideal gas with constant specific heats. Evaluate the specific heats at 100° F. Determine the amount of work done on the gas in Btu and the heat transfer to the gas in Btu. Neglect changes in kinetic energy and potential energy.

3. An ideal gas with constant specific heats undergoes a process from an initial pressure and specific volume of 80 kPa and 40 m3/kg to a final specific volume of 20 m3/kg. During the process, the hydrogen’s pressure and specific volume are related through the equation given below. In the equation, ?? and ?? are the initial pressure and specific volume of the hydrogen, respectively. Determine the specific work done on the gas in MJ/kg and the specific heat transfer to the gas in MJ/kg. The ideal gas has a molar mass of 2.0 kg/kmol and a specific heat at constant volume of 7.5 kJ/(kg∙K). Neglect changes in kinetic energy and potential energy.

   ? = ?? ⋅ [2 − (?/??)]

2. A contractor has a contract to remove and replace the existing landscape and
sidewalks around an office building. The work includes demolition of the
existing landscaping and sidewalks, importing fill and grading around the
office building, constructing new concrete sidewalks, and new landscaping.
The contractor uses the cost codes in Figure 2-6. The original estimate for the
demolition was $30,000 and a $5,000 change order has been approved to
remove some unexpected debris found during the demolition. The
demolition work has been completed at a cost of $33,562. The original
estimate for the fill and grading was $17,500 and a $2,000 change order for
importing additional fill to replace the debris has been approved. The fill and
grading costs to date are $17,264 and the cost to complete has been
estimated at $2,236. The original budget for the labor to pour the concrete
was $19,200 and no changes have been made. The concrete labor has been
subcontracted out for $19,200, for which the contractor has received a bill
for $15,200. The original budget for the concrete for the sidewalks was
$9,900 and no changes have been made. The contractor has spent $7,425 for
concrete and estimates that $1,950 of concrete will be needed to complete
the project. The original estimate for the landscaping was $37,500 and no
changes have been made. The landscape work has been subcontracted out for
$37,500. The landscaping work has yet to start and no bills have been
received. Determine the total estimated cost at completion for the project
and the variance for each cost code.
