Final answer:
To determine if the flow of air through the laminar hood is laminar, calculate the Reynolds number (NR). For NR values below 2000, the flow is laminar. For NR values above 3000, the flow is turbulent. For NR values between 2000 and 3000, the flow can be either laminar, turbulent, or both.
Step-by-step explanation:
To determine if the flow of air through the laminar hood is laminar, we can calculate the Reynolds number (NR). The Reynolds number is calculated using the equation NR = 2pvr, where v is the velocity of the air, r is the radius of the hood, and p is the density of the air. For NR values below about 2000, the flow is laminar. For NR values above about 3000, the flow is turbulent. For values of NR between 2000 and 3000, the flow can be either laminar, turbulent, or both.
