An equation for the frictional pressure loss Δ p (inches H2O) in a circular duct of inside diameter d (in.) and length L (ft) fo

r air flowing with velocity V (ft/min) is Δp = 0.027( L d 1.22)(V V0)1.82,where V0 is a reference velocity equal to 1000 ft/min. Find the units of the "constant" 0.027.

Answer:

The units of the constant "0.027" is inchH₂O·inch^(1.22)/fit

Explanation:

The constant has to be consistent with all the other units of this equation:

\Delta P [InH_2O]=\displaystyle 0.027[x]\frac{L[ft]}{(d[in])^{1.22}}(\frac{v[ft/min]}{v_0[ft/min]})^{1.82}

Therefore:

[InH_2O]=\displaystyle [x]\frac{[ft]}{([in])^{1.22}}(\frac{[ft/min]}{[ft/min]})^{1.82} \leftrightarrow [x]=\frac{[InH_2O][in]^{1.22}}{[ft]}

A 55.0-kg box rests on a horizontal surface. The coefficient of static friction between the box and the surface is 0.300. What h
MariettaO [177]

Answer:

161.86 N

Explanation:

mass of box m= 55.0 kg

weight of the box, mg= 55×9.81

g here is acceleration due to gravity =9.81 m/sec^2

coefficient of friction between the box and the surface μ= 0.3

the friction force F_s= μmg= 0.3×55×9.81

=161.86 N

to move the ball horizontal force required is 161.86 N

Jlenok [28]

Answer:

-30°C

Explanation:

F-32/180 =C-0/100

or, -22-32/180=C/100

or, -54/180*100=C

or, -0.3*100=C

therefore, C= -30

-22°F = -30°C
