A flushing plan includes 300 ft of pipe with a 2 in. inside diameter. Using 7.48 gal/cf, what water volume is inside the pipe?

Correct Answer

B) 49.0 gal

Radius is 1 in. = 1/12 ft. Volume is pi x (1/12)^2 x 300 = 6.545 cf. Gallons are 6.545 x 7.48 = 49.0 gal. Other choices use the wrong radius, confuse diameter with radius, or skip the gallon conversion.

A
39.2 gal
B
49.0 gal
C
58.8 gal
