1. You own a mechanically ventilated swine facility. The dry bulb temperature inside the facility is 50 degrees F and outside is only 30 degrees F. Inside you have a relative humidity of 70% and outside the relative humidity is 20%. To keep the humidity from getting any higher you need to remove 12 gallons of water per hour from the facility with the ventilation air. At what rate (cfm) must the fans pull inside air out of the building? 2. A producer has a barn for sheep and lambs. The producer wants to use evaporative cooling to cool the barn. If the outside air has a dry bulb temperature of 90 degrees F and a relative humidity of 40%, what is the lowest temperature that the producer can get using the evaporative cooler?

We all use gps today, even if we don't drive yet. i bet you have been in the car with a parent and they have asked you to get out your phone to find a specific location. in your car, on the phone, you are using a very sophisticated technology. gps satellites circle the earth twice a day in a very precise orbit and transmit signal information to earth. gps receivers take this information and use trilateration to calculate the user's exact location. essentially, the gps receiver compares the time a signal was transmitted by a satellite with the time it was received. the time difference tells the gps receiver how far away the satellite is. now, with distance measurements from a few more satellites, the receiver can determine the user's position and display it on the unit's electronic map. what type of signal is utilized by the gps satellite?
