A fluid is flowing through a pipe and faces a constriction that reduces the diameter by half. Calculate the change in flow velocity if the flow is incompressible.
💡 Hint: Remember that the flow rate must remain constant.
In a control volume, a fluid is entering with a mass flow rate of 5 kg/s and exiting with 4 kg/s. Calculate the change in mass within the control volume over 10 seconds.
💡 Hint: Consider how mass flows in and out of the control volume.
