The distance through which the total loss of momentum per second be equal to if it were passing stationary plate is known as​

Answer 1

Momentum Thickness

Explanation:

Momentum thickness is that the distance through which the entire loss of momentum per  second be adequate to if it were passing a stationary plate.

The expression for the momentum thickness is,

$\theta = \int\limits^\delta_0 {(\dfrac{u}{v}) (1 - \dfrac{u}{v}) } \, dy$

Momentum thickness is defined in reference to the momentum flow within the physical phenomenon.

This rate is a smaller amount than the speed that might occur if no physical phenomenon existed, when the speed within the vicinity of the surface, at the station considered, would be adequate to the mainstream velocity.

Near the bluff body, momentum thickness decreases, which denotes maximum momentum transfer and because it becomes negative, it corresponds to recirculation zone.
