Question:
Circulation is referred to as
Circulation is referred to as
Show Hint
Vorticity is the curl of the velocity field; its surface integral gives circulation.
Updated On: June 02, 2025
- Flux of vorticity
- Velocity field
- Divergence of velocity
- Mass flux
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Circulation represents the integral of velocity along a closed curve, which equates to the flux of vorticity through the area bounded by the curve.

- In a water tank, an air bubble rises from the bottom to the top surface of the water. If the depth of the water in the tank is 7.28 m and atmospheric pressure is 10 m of water, then the ratio of the radii of the bubble at the bottom of the tank and at the top surface of the water is (Temperature of the water in the tank is constant)

- An oil of density \(870 \, {kg/m}^3\) and viscosity \(0.036 \, {Pa.s}\) flows through a straight pipe of 10 cm diameter and 1.5 km length at the flow rate of 250 liters per minute under the steady and incompressible flow conditions.
To control the flow rate of oil, a valve is fixed at the middle of the pipe causing no change in the total length of the pipe. The total head loss measured across the two ends of the pipe is \(11.60 \, {m}\). Using gravitational acceleration as \(10 \, {m/s}^2\), the minor head loss contributed by the presence of the valve in m {(rounded off to 2 decimal places) is ..........}- GATE XE - 2025

A fixed control volume has four one-dimensional boundary sections (1, 2, 3, and 4). For a steady flow inside the control volume, the flow properties at each section are tabulated below:
The rate of change of energy of the system which occupies the control volume at this instant is \( E \times 10^6 \, {J/s} \). The value of \( E \) (rounded off to 2 decimal places) is ........- GATE XE - 2025
