Question

The horizontal flow of fluid depends upon:

• A. pressure difference
• B. amount of fluid
• C. density of fluid
• D. all of these

Answer 1

The correct option is A pressure difference

The density and amount of fluid do not change in horizontal flow. This is the properties of fluid.

The horizontal flow depends on the pressure difference. If there is difference in height at any two points in horizontal flow then there will be pressure difference between those two points.

Therefore option $A$ is correct.
