power required to move a air with speed of 10.5m/s and pressure of 4550Pa with a duct size of 1.4m*1.4




To calculate the power required to move air through a duct with the given parameters, we follow the same process as before.

### Given Data:
- **Air velocity (v):** 10.5 m/s
- **Pressure (P):** 4550 Pa
- **Duct dimensions:** 1.4 m × 1.4 m
- **Efficiency (\(\eta\)):** Assumed to be 100% (or 1) if not given.

### Step 1: Calculate the Cross-sectional Area of the Duct
The duct is square-shaped:
\[
A = 1.4 \, \text{m} \times 1.4 \, \text{m} = 1.96 \, \text{m}^2
\]

### Step 2: Calculate the Volume Flow Rate (Q)
The volume flow rate is given by:
\[
Q = A \times v = 1.96 \, \text{m}^2 \times 10.5 \, \text{m/s} = 20.58 \, \text{m}^3/\text{s}
\]

### Step 3: Calculate the Power
The power required is:
\[
\text{Power} = \frac{P \times Q}{\eta} = \frac{4550 \, \text{Pa} \times 20.58 \, \text{m}^3/\text{s}}{1} = 93639 \, \text{Watts} = 93.64 \, \text{kW}
\]

So, the power required is **93.64 kW**.
