A gasoline storage tank drains by gravity to a tank truck; see the drawing. The

pipe line between the tank and the truck is $100m$ of $0\mathrm{.}1m$ diameter

commercial steel pipe. The properties of gasoline are given as$,$ density $=720$

$k\frac{g}{m}3,$ dynamic viscosity $=0\mathrm{.}0006k\frac{g}{m}.s.$ Both tank and truck are open to

the atmosphere, and the level in the tank is $10m$ above the level in the

truck. What is the volumetric flow rate of the gasoline?.
