    (B) False

    Explanation:

    An unstable flow is a flow process where the properties of the flow is not stable. from this example or question, the input flow output flow are not equal or the same

    Unstable flow is can be refereed as a flow that is transient. because the main properties of interest which includes the volume of the flow through the pipe is not the same so this type of low gives more concern to the person carrying out the study, and time of flow.

    False

    Explanation: An unstable flow is a flow process where the properties of the flow is unstable, in this case the flow input and flow output are not equal.

    Unstable flow is also known as transient flow process because the main properties of interest which includes the time of flow and the volume of the flow through the pipe is not the same so this type of low gives more concern to the person carrying out the study.
