In the boiler of a power plant are tubes through which water flows as it is brought from a saturated liquid condition at 1000 lbf/in.2 to 1300°F at essentially constant pressure. Combustion gases passing over the tubes cool from 1740°F to temperature T at essentially constant pressure. The mass flow rates of the water and combustion gases are 400 and 2995.1 lb/s, respectively. The combustion gases can be modeled as air behaving as an ideal gas. There is no significant heat transfer from the boiler to its surroundings. Assuming steady state and neglecting the effects of motion and gravity, determine
(a) the exit temperature T of the combustion gases, in °F.
(b) the exergy destruction rate, in Btu/s.
(c) the exergetic efficiency given by Eq. 7.27. Let T0 5 50°F, p0 5 1 atm.

An expansive soil has an active-zone thickness of 10 ft. The natural moisture content of the soil is 25% and its liquid limit is 60. Calculate the free surface swell of the expansive soil upon saturation.
A car has an initial speed of 25 m/s with a constant deceleration of 3m/s^2. Determine the velocity of the car when t=4s. What is the displacement of the car during the 4 second time interval? How much time is needed to stop the car?
A vertical, closed-loop geothermal heat pump is under consideration for a new 50,000-ft2 school building. The design capacity is 100 tons for both heating and cooling.
