Answer:

1425.78 N.m

Explanation:

Moments of force is calculated as ;

Moments= Force * distance

M= F*d

The S.I unit for moment of force is Newton-meter (N.m)

Given in the question;

Force = 72 lbs

1 pound = 4.45 N

72 lbs = 4.45 * 72=320.4 N

Distance= 15 ft

1ft= 0.3048 m

15 ft = 15*0.3048 = 4.57 m

d= 4.57 m

M= F*d

M=320.4*4.57 =1425.78 N.m

Flow and Pressure Drop of Gases in Packed Bed. Air at 394.3 K flows through a packed bed of cylinders having a diameter of 0.012
devlian [24]

The pressure drop of air in the bed is  14.5 kPa.

<u>Explanation:</u>

To calculate Re:

R e=\frac{1}{1-\varepsilon} \frac{\rho q d_{p}}{\mu}

From the tables air property

\mu_{394 k}=2.27 \times 10^{-5}

Ideal gas law is used to calculate the density:

ρ = \frac{2.2}{2.83 \times 10^{-3} \times 394.3}

ρ = 1.97 Kg / m^{3}

ρ = \frac{P}{RT}

R = \frac{R_{c} }{M} = 8.2 × 10^{-5} / 28.97×10^{-3}

R = 2.83 × 10^{-3} m^{3} atm / K Kg

q is expressed in the unit m/s

q=\frac{2.45}{1.97}

q = 1.24 m/s

Re = \frac{1}{1-0.4} \frac{1.97 \times 1.24 \times 0.0127}{2.27 \times 10^{-5}}

Re = 2278

The Ergun equation is used when Re > 10,

\frac{\Delta P}{L}=\frac{180 \mu}{d_{p}^{2}} \frac{(1-\varepsilon)^{2}}{\varepsilon^{3}} q+\frac{7}{4} \frac{\rho}{d_{p}} \frac{(1-\varepsilon)}{\varepsilon^{3}} q^{2}

\frac{\Delta P}{L}=\frac{180 \times 2.27 \times 10^{-5}}{0.0127^{2}} \frac{(1-0.4)^{2}}{0.4^{3}} 1.24 +\frac{7}{4} \frac{1.97}{0.0127} \frac{(1-0.4)}{0.4^{3}} 1.24^{2}

= 4089.748 Pa/m

ΔP = 4089.748 × 3.66

ΔP = 14.5 kPa
