The rectangle above is a control volume. Flow 1 is 2.7 slugs/sec while
flow 2 is 8.4 slugs/sec. The fluid has density 1.3 slugs/ft³.
Determine the volumetric flow rate of flow 3 in ft³/sec.
Answer with a positive number if the flow is out of the control volume
and a negative number if the flow is into the control volume.
Your answer should include at least one digit after the decimal place.
