Question 79880: please help me out with this i need to turn this in soon possible and also this will help me in the rest homework to. thank u
1. Hydrodynamics is the branch of physics that studies the behavior of liquids that are in motion. For example, The Principal of Continuity in Liquid Flow states that the velocity of a liquid flowing through a pipe increases as the cross-sectional area of the pipe decreases, and decreases as the cross sectional area of the pipe increases.
On a given day, a fire department uses the same pump to put out two fires. The rate of water is given by the rational function:
f = 1250/A
where r is the rate of water in gallons per minute, and A is the cross sectional area of the hose in square inces. Does the function obey the Principal of Continuity in Liquid Flow?
2. During the morning fire, the fire department used a hose with a cross sectional area of 5 square inches. What was the velocity of the water?
3. During the evening fire, the velocity of the water was 100 gallons per minute. What was the cross sectional area of the hose?
