Answer 1

Explanation:

Conservation of Momentum using Control Volumes

Conservation of Linear Momentum

Recall the conservation of linear momentum law for a system:

In order to convert this for use in a control volume, use RTT with B = mV, beta = V

we get:

NOTE: Recall that at any instant of time t, the system & CV occupy the SAME physical space.

So, the forces of the system are the same at the forces of the control volume at a given instant.

For a fixed control volume we have the following equation:

This is a vector equation so it has three components.

First, let us consider the component in the X-direction. We will drop the cv subscript since it is understood. The conservation of linear momentum equation becomes:

Notice that the V dot n term is a scalar, not a vector.

Next, let us consider the component in the Y-direction. The conservation of linear momentum applied to the y-direction
