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.
Hint: Use continuity
A wind turbine produces 1.86 MW when the wind
speed is a speed v. Assuming the same conditions for
the turbine (same size, same power coefficient and
same air density) how much power would this turbine
produce is the wind speed doubled? Round off your
answer (in MW) to 2 decimal places. Do not write the
unit.
