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?

answer: at 24 february, 2014 the population gets twice of its initial population.

explanation:

since we have given that

the population for alpha city, t years after january 1, 2004 is given as

first we find out the initial population, i.e. t=0,

so, our quadratic equation becomes,

according to question, we have said that if the population has twice its initial population, then it becomes

so, time taken to reach this above mentioned population is given by

now, we know that time can't be negative so, we take t=9.149 years.

hence, at 24 february, 2014 the population gets twice of its initial population.

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
