In a steady flow open system, a fluid moves between two boundaries. In boundary 1: Az = 0.028 m², V1 = 32.5 m/min, vị = 0.025 m²/kg, and P1 = 300 kPaa. In boundary 2: Az = 0.056 m?, density = 3.2 kg/m³, and P; = 100 kPaa. Determine a) the mass flow rate; b) the velocity in boundary 2; c) the change of kinetic energy between boundaries; and d) the change in flow energy between boundaries.

In a steady flow open system, a fluid moves between two boundaries. In boundary 1:
A = 0.028 m², V1 = 32.5 m/min, vị = 0.025 m³/kg, and P1 = 300 kPaa. In boundary 2: Az
= 0.056 m?, density = 3.2 kg/m?, and P2 = 100 kPaa. Determine a) the mass flow rate; b)
the velocity in boundary 2; c) the change of kinetic energy between boundaries; and d)
the change in flow energy between boundaries.
A 100 liter tank contains a mixture of saturated liquid water and saturated steam at
370 °C.
a) Find the mass of each phase if their volumes are equal
b) Find the volume occupied by each phase if their masses are equal.
Given: v = 2.213x103 m³/kg; vg = 4.925x103 m³/kg
