Why might construction crews want to install pipes before the foundation is poured
A. Pipes form an important component of the structural integrity of a foundation.
B. All utilities, including electrical and HVAC, are installed before the foundation is laid.
C. Plumbing must feed into municipal water and sewer lines buried below the foundation.
D. Plumbing crews are more expensive than concrete masons; therefore it is cheaper if they do their work first.

To save energy, the air supply to a 2000 ft office has been shut off overnight and the room temperature has dropped to 40°f. in the morning, the thermostat is reset to 70°f and warm air at 120 f begins to flov in at 200ft'/min. the air is well mixed within the room, and an equal mass flow of air at room temperature (changing with time) is withdrawn through a return duct. the air pressure is nearly 1 atm everywhere. ignoring heat transfer with the surroundings and kinetic and potential energy effects, estimate how long it takes for the room temperature to reach 70°f. plot the room temperature as a function of time.
