change in volume of tank
= (5000)(4400)(21) cm^3
= 462,000,000 cm^3
= 462,000 L
15 km/hr
= 1,500,000 cm/hr
Volume moved
= 1,500,000(49π) cm^3/hr
time to fill 462,000,000
= 462,000,000/1,500,000 hrs
= 308 hrs
check my arithmetic
Water is flowing at the rate of 15km/hr. Through a cylindrical pipe of radius 7cm into a rectangular tank which is 50m long and 44m wide.In how many hours will the water label in the tank raised by 21cm
