Question

In an ideal fluid flow, the:

• A. surface tension forces are zero.
• B. pressure is zero
• C. Viscosity is zero.
• D. pressure increases linearly with depth

Answer 1

Answer:

C. Viscosity is zero.

In an ideal fluid flow, viscosity is zero. This means that there is no existence of shear force due to vanishing viscosity. Pressure is equal everywhere in an ideal flow. Surface tension forces are zero in an ideal fluid flow. Pressure increases linearly with depth is not true for an ideal fluid flow.
