Ichetucknee Springs is a Florida State Park that is about 30 miles northwest of Gainesville. One of the most popular activities in the park is floating down the Ichetucknee River in an inner tube. Given that the river is about 40 feet wide, 6 miles long, and the water is 72°F, calculate the average velocity of the water (in meters/second) if it takes a tuber 3 hours to float from the launch to the exit. Then, calculate the average volumetric flow rate in (m3/second) of the water, making sure to clearly state all assumptions.
Calculate length of the pipe required to bring down the concentration of chlorine from 6x105 CFU/L to the permissible value of 2500 CFU/L. It is given that the velocity of flow through the pipe is 0.7 m/s and the rate constant is 0.25 per min.
a. The diameter of a 3 meter pipe decreases from 450 mm to 150 mm. If the velocity is to decrease uniformly in a linear manner, draw the diameter profile at each 500 mm length interval along the pipe. Discharge is 150 liters per second. b. The same venturi meter described in letter a is used to measure the discharge for a length of pipeline that was suspected to have had water stolen through an illegal connection. Before said suspected illegal connection, a mercury difference of 350 mm was observed while a mercury difference of 200 mm was observed afterwards. Estimate the stolen volume of water per day.
