Answer 1

(3) Potent energy per unit volume

Step-by-step explanation:

The kinetic energy, pressure and flow speed all change with cross-section area so they are not constant over time. Because the flow is in a horizontal pipe, the height never changes so (3) Potent energy per unit volume is constant.

Answer 2

Option C

Step-by-step explanation:

Mark the line horizontal pipe.

• Means the height is constant
• Potential energy depends upon height.
• So potential energy also remains unchanged
