water flow through a cylindrical pipe of internal radius 3.5cm at 5m per second calculate the volume of water in litres
Answers
In one sec. length of water flow in pipe = 5 m
radius = 7/2 = 3.5 cm = 0.0035 m
volume of water flow per sec = π r² h
= π(0.0035)² ×5
=192.5× 10^(-6) m³
volume of water discharged per min
= 192.5× 10^(-6) m³×60
= 11.55×10^(-3) m³
= 0.01155 m³
=11.55 Liter
volume of tank = 4×3×2.31 = 27.72 m³
∵1m³ = 1000 Liter
volume of tank = 27720 Liter
time to fill the tank = 27720/11.55
= 2400 minutes
= 2400/60
= 40 hours
hope this helps :)
