2.) A fluid moves in a steady manner between two sections in a flow line. At section 1: A2 = 10 ft?, V = 100 fpm, vl = 4 ftp/lb
At section 2: A2 = 2 ft², P2 = 0.20 lb/ft?
Calculate (a.) the mass flow rate, and
(b.) the speed at section 2

Explanation:

= Area of section 1 =

= Velocity of water at section 1 = 100 ft/min

= Specific volume at section 1 =

= Density of fluid =

= Area of section 2 =

Mass flow rate is given by

The mass flow rate through the pipe is

As the mass flowing through the pipe is conserved we know that the mass flow rate at section 2 will be the same as section 1

The speed at section 2 is .
