Explanation / Answer

Ans 7.2

Volume of tank = 500 gallon

Flow rate = (500 - 250) gal / 2 hr

= 250/2 = 125 gal/hr

If volume is = 300 gal

Flow rate will be same for the same tank

Flow rate = 125 gal / hr

125 gallon will drain in 1 hr

After 1 hr

Volume remain in tank = 300 - 125 = 175 gal

remaining questions are not part of problem 7.2.

you will have to provide the details of example 2, example 3 and example 4 for 7.3, 7.4 and 7.5 respectively
