Question

Water is poured into the cuboidal tank at the rate of $50L$ per minute. If the volume of the tank is $12.8m^2$, then find the time taken to fill the tank completely.

Answer 1

$rateofwaterpoured=50Lperminute=50\cdot {10}^{-3}\left(\frac{m^3}{min}\right)=\left(\frac{5\cdot {10}^{-2}}{60}\right)m^3/sec\therefore Timetakentofillthetank=\left(\frac{12.8}{\left(\frac{5\cdot {10}^{-2}}{60}\right)}\right)sec=15360sec256min=4.26hour$
