Water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer. the manometer shows a height difference of 6 inches. at the inlet of the manometer the diameter of the pipe is 1 inch and at the exit of the manometer the diameter of the pipe is 0.5 inches. assuming negligible friction, what is the flow rate (gpm) in the pipe?

60.12 miles

Explanation:

Using the calculation formula shown below:

\frac{N_{o} }{N_{t} } }" alt="log_{2}" />\frac{N_{o} }{N_{t} } }" />

where:

is the half life, is the original amount of F-18, and is the remaining amount of F-18 at time t.

Generally, F-18 has an half life of 1.83 hours.

Therefore:

\frac{100}{68} = 1.02 hours" alt="log_{2}" />\frac{100}{68} = 1.02 hours" />

Therefore using a speed of 59 miles/hour, the closeness of the hospital is:

distance = speed*time = 59*1.02 = 60.12 miles
