Expert Solution

Answer to Problem 11.6CP

The function that is dimensionless is $TρD5ωP2=fcn(s)$

Explanation of Solution

Given Information:

Diameter=1ft

Coupling rate=2500r/min

Density=56lbm/ft3

Concept Used:

$π1=ρaDbωpcT$

$where,ρ=densityD=diameterωp=speedT=torque$

Calculation:

The number of pi in the groups are calculated.

$N=k−r$

Where,

k=total number of variables

r=total number if references

Calculating we have,

$M0L0T0=(ML−3)aLb(T−1)c(ML2T−2)$

$=(Ma+1L−3a+b+2T−c−2)$

$=(MaL−3a+bT−c)$

By equating M and T coefficients we get

$a=0,c=0$

Calculation:

Angular velocity unit conversion:

$ωp=2500×160⇒41.7r/s$

Density unit conversion:

$ρ=56lbm/ft3⇒1.74slugs/ft3$

With the equation:

$TρD5ωP2=901.74×15×41.72⇒903025.67$

$=0.0298$

$=0.0298$

From the table the slip is given as 5%:

s%	0	5	10	15	20	25
$TρD5ωP2$	0	0.0298	0.0911	0.146	0.192	0.225

Calculating the given values:

$TρD5ωP2=9001.74×58.32×15⇒9005914.069$

=0.152

From the table we have, 15%.

Conclusion:

The slip using the table is calculated.

Answer 19

Explanation of Solution

Given Information:

Coupling runs at 3600r/min and torque is given as 900ft.lbf

Concept Used:

$TρD5ωP2where,ρ=densityωP=angular velocitys=slip$

Calculation:

Angular velocity unit conversion:

$ωp=2500×160⇒41.7r/s$

Density unit conversion:

$ρ=56lbm/ft3⇒1.74slugs/ft3$

With the equation:

$TρD5ωP2=901.74×15×41.72⇒903025.67$

$=0.0298$

From the table the slip is given as 5%:

s%	0	5	10	15	20	25
$TρD5ωP2$	0	0.0298	0.0911	0.146	0.192	0.225

Calculating the given values:

$TρD5ωP2=9001.74×58.32×15⇒9005914.069$

=0.152

From the table we have, 15%.

Conclusion:

The slip using the table is calculated.

Expert Solution

Answer to Problem 11.6CP

Diameter = 1.36ft.

Explanation of Solution

Given Information:

Power=3000r/min

s=5%

Torque=600ft-lbf

Concept Used:

$TρD5ωP2where,ρ=densityωP=angular velocitys=slip$

Calculation:

With the equation:

$TρD5ωP2=6001.74*D5*5020.0298=6004350*D5D=1.36ft$

Conclusion:

Thus, the diameter is calculated.
