Water is found to move through a pipe at a speed of 9m/s where the temperature of the water at the entrance is found to be $50^{\circ}$ C, and pressure 180 kPa where the pipe diameter is 0.50m. At the exit the pressure was found 160kPa, and temperature at the $100^{\circ}$ C. Determine the volume flow rates of water at the inlet and exit, the velocity at the exit, and the mass flow rate.

$T_1=50^\circ\text{C}$
$P_1 = 180 \ \si\kPa$
$V_1 = 9 \ \si\m/\si\s$
$T_1=100^\circ\text{C}$
$P_2=160 \ \si\kPa$

Given:

$T_1=50^{\circ}$ C

$P_1=180kPa$

$V_1=9m/s$

$D=0.50m$

$T_2=100^{\circ}$ C

$P_2=160kPa$

Find:

Determine the volume flow rates of water at the inlet and exit, the velocity at the exit, and the mass flow rate.
